I’m so glad the hypnosis is done and people are finally waking up to realizing that BW was THAT show and overhated for no reason but we gonna have to finally talk about how AG was the weakest link in terms of being memorable and I mean minus BF and a Pokegirl having a goal arc.
Who are you even talking about?
A common sentiment has always been that Best Wishes Season 1 was quite good, but the main problem was that it torched Ash's progression. That's why it left a bad taste in the fandom, and will never stop being a criticism of BW.
I'm fairly certain Cameron/Unova League and BWS2 especially DA! is still seen more unfavorably.
At least OS has charm, DP has being amazing, BW/XY has controversy and SM/JN being major wins for Ash saves them but….what happened during that series?
A lot, if you were paying attention.
AG was a middle chapter of sorts. Once the writing staff realized the anime wasn't going to end during OS and going to be in for the long haul, AG was presented as a staging ground for Ash's ongoing character development and a template for years of anime to follow. Was it perfect? Absolutely not, but the writing in the Ashnime has
never been anything spectacular.
AG was the season where Ash steps up as a Trainer. He wasn't handheld by his companions; he captured and raised a team by himself (he wasn't carried by a Charizard who trained at the Valley); and he proved the merits of his training at the Hoenn League where he narrowly lost to the eventual winner. It was the only time it was ever justified for Ash to exclusively use his regional team at a league, and the show expressed it as much. Ash's Hoenn team was one of the most well-balanced (if not the most alongside the SM team) in terms of personality and skill.
Once that was done, he went onto the Battle Frontier. While
@Almighty Zard is right that it wasn't perfect in execution, it nevertheless remains the best presentation of Ash juggling through multiregional teams to great effect. So many people wanted
Journeys to be like Battle Frontier, with Ash using reserves throughout the PWC. Ash defeating Brandon with the Gang of Four was a huge coming-full-circle moment, and completing the Battle Frontier was arguably Ash's best achievement until he became the Champion of Alola.
Ash was well-balanced between being still snarky and animated, but also increasingly mature, and he had a nice mentor/mentee relationship with May. You could even argue that Contestshipping did a mutual budding romance better than Amourshipping a decade later. The humor was low-key great as well. AG was the first season to give the female companion her own dedicated goal arc (a big deal), had less fillers than Johto, continued to have continuity to OS, and set up DP so well.
