In regards to complaints about Clemont and Bonnie not receiving any "development",. People wil always focus most on characters which have concrete storyline. More episodes dedicated to their development, reveal of pokemon qualities, various sodes to their personalities and some in advance preconceived route through which characters will be taken.
With fans of pokemon series wanting clear cut simplified version of character development(sadly), rather than reading between lines in episodes,. observing subtle changes in characterization which happens gradually and slowly over long period of time analyzing epiusodes and certain events which indicated two things;
-character gaining something from it
-being showed to have dilemma and internal breakes inside itself inhibiting him from moving fiorward.
Delivering more profined and complicated version of growth where characters dont grow just through specific episodes, but through long period in way they perceive world, learn new things and build on friendship with others. With changes starting to be noticeable after some time.
For same reason people developed entirely wrong perception of other past characters like Misty not developing, simply because they often took eisodes focusing on her or playing side role in them for granted.
As something "insignificant and filler which can be skipped"(this holds truth especially to Johto with episodes when she met Sakura, argued with fire trainer Egan,reflected on her friendship with Ash in episodes when battling for Totodile or traveling through Whirl islands, taking care of Wooper in kindergarten, saving Marill and developing close friendship overcoming her fruistration and initial dislike for example). Ignoring changes in dialogue, change of characterization and dealing with trials and struggles on individual episode basis.
Which showed maturity in character, new layer in her sassy, flirty, kindhearted and emotional aspect of personality dealing with personal issues, flaws and reaching new dimension to itself as time went on.
So im not surprised why people are doing exact same mistake for Clemont and Bonnie, overlooking those periodical, but very crucial moments where we get to know better this characters, dive into their history, reasonong behind being persons they are today and their dreams they strive to accomplish.
Clemont was in beginning completely insecure character, lacked courage for anything and had little to no faith in his trainer abilities. But now after almost 60 episodes after he gained more of his own identity as character, learned to be more compassionate about pokemon and resolved not escaping from danger. Fixing broken bonds left on open note in relationships with past pokemon, came to realization to better understand his own feelings and grew in stronger, more confident character.
Backed by various episods such as risking life to save Chespin, wanting to redeem himself after helping TR in building Helioisk mecha. Reconciled with long lost friend Luxray or came to realization how Chespin doesnt disike him or view as bad trainer which cannot offer him care, support and shelter.
Became more engaged in various activities finding himself in various danger situations such as entering Summer camp tasks, trying to ride pokemon like Gogoat, ending into Victreebel mouth etc. Which while being comedy situations showed gradual change in character becoming more brave and proactive.
In comparison Bonnie became better understanding of her own brother strengthening on bond beteen themselves with writers exploring through various episodes on how much Clemont is protective over his little sister. Which doesnt hide pride of her brother accomplishments .
She also get to explore pokemon world and get to better know pokemon establishing close bond with several of them. Putting their own happiness and needs before her own requests showing development in stopping to be as irrational and in some situations selfish as it used to be case in earlier episodes.
Moments such as letting Flabebe go to its owner, befriending Espurr, joining group of kids in saving Laspras finding way to its family, encouraging Ash Fletching not to give up and awaken fighting spirit inside itself when battling Talonflame illustrated this pretty well.
So siblings definitely developed over course of XY series, as much as some tend to overlook it.
The only flat character on the show in recent years was DP-era Brock. No character has ever gotten as flat as he was back in DP. Its almost hard to think OS Brock and DP Brock were the same character.
Care to explain what you found so "flat" about Brock? I certainly didn't noticed any radical changes to Brock personality in Sinnoh still being wise, caring, mature, flirtatious and assettive having strong moral views to his character.
As evidenced in several episodes such as in scolding Cherubi girl which thought looks matter the most when it comes to pokemon. Helping Ditto trainer or maid with Miltank to better understand their pokemon. Risking his life to find Cherry berries for Ash sick pokemon or playing important role in stopping Team Galactic not just in grand finale, but episodes before that as well. Such as in preventing them from getting Spear Pillar with Ash aid.
Teaching Dawn importance of taking care of helpless pokemo like Shieldon etc.
Being involved in various funny situations such as in drawing Dawn into "Takeshi Paradise!" performance or figuring reason behind pokemoln like Snower pulling jokes on Ash and rest of group.
Brock was maybe underused, but he was hardly "flat lifeles" character as you make it seem to be in DP saga. Far from it.
Tbh, I never found brock interesting, outside a few funny lines Id almost rather Ash travelled alone in OS, all he would need is to catch an onix and starmie, and the series would prolly have been better for it imo.
So basically keeping Ash as only part of equation with no companions to interact to. No exploration of feelings, inner doubts and character personalities as they help flesh each other out. Developing through it?
I disagree with such constatation. If anything Misty and Brock were one of best things which could had happened to pokemon imo contributing heavily to pokemon appeal and popularity.
With their eccentric characters, unique interersts in life, original dreams in showing how pokemon can be raised and become succesful with them taking alternate route compared to being ordinary trainer.
Strong personalities containing underlying depth, dive into character mind and variety of expressions(especially in Misty case) delivering lot of flare, drama, diversity of emotions, suspension, care and optimism in group chemistry. Enriching on anime atmosphere.
All wrapped up with sad backgrounds and insecurities with which people could relate themselves with feeling sorry for characters, funny pokemon and important role in helping Ash to learn how to take care of himself becoming stronger battler.
Were all important things justifying rightfully their place in pokemon history.
Whoops, did I just Bash OS, good, hope you people get this is what BW fans go through 5 times a day browsing these forums. It's even in the f*cking title, move the hell on, your post doesnt get better if you add a BW complaint, it's a damn waste of time tbh.
Retaliation in bashing other sagas with same measure is hardly way in making people stop disliking pokemon series you may had liked. It only deepens jazz and intolerance between fans.
Not to mention it would be big understatement to say how OS fans are ones responsible for flack BW era of pokemon is getting. If anyhing this forum has way more DP supporters than its case for any other series.
