I have come to accept that the overwhelming majority of the show consists of anti-climaxes, the only times we get big even handed face offs and what not are the actual official competitions where the writers know they absolutely positively HAVE to make it eventful, and even then if they can find an excuse not to, they'll damn well use it.
Now anti climaxes aren't exactly a bad thing, so long as they're not an excuse to avoid developing the characters and plot (
one my favourite anti climaxes since childhood for example) but that's the common issue with Pokemon, it often plots out each story in a way so that the protagonists don't really have to get too involved or entertaining besides generic contributions like calling attacks or doing things any generic placeholder could do, which makes them very dull after a while. Situation is too complicated? Have Team Rocket interfere. Even Team Rocket putting up a not-completely-pitiful fight? Plot armour the twerps so it's back to square one. This tends to happen even in stories that seem like they are meant to be climatic or fulfilling about the protagonist's roles, when half the time most of their role that didn't consist of physics bending for them had barely any substance or entertainment value at all. Even worse they don't even make use of the anti climatic nature, remember when the twerps used to snark at how crappy Team Rocket's schemes were or how a lot of the COTD's issues were dumb or preventable? No they take it damn well seriously and by the script now which takes out even more of the fun and makes the whole thing like watching some machinery following some function on a loop.
SM is mundane, but intentionally so, and it tries to make each character's contribution to the story different and amusing. This of course doesn't always work, especially with a large cast, but it does have a better success rate and does help us connect to the characters and feel they are remarkable. The issue is that it still doesn't really deliver in many points it is SUPPOSED to be climatic and the characters are supposed to take a big step in development, even if it does work on subtle and gradual levels at times.
My hope is that SM is baby steps, and perhaps next series they'll be a bit better at writing more ambitious stories while keeping up the progression rate, all while still making them character driven.
