Alain's...
- ...pretty much everything about him: battle prowess, lack of scenes with his other Pokemon, super Charisexual, stupid cliche goal, an absurd powerful bypasser to the league who won everything and gave everyone in there middle fingers, empty shell of occasional hatred, what the hell is that outfit?, hell I like Sasuke from Naruto better in the angst department!

Extremely rushed league.
Showcases, and their lack of male rivals.
Showcase rivals in general.
The Gosh darned Korrina arc. USE YOUR STUPID AURA ONCE, YOU DUMB JACKAL. STOP USING YOUR STONES!
Mary Sue Aria. She lifts a finger, she regains her title. Serena pulls all the stops (with fire, again) but it's not enough.
Lack of jerkass rivals. Well, they DO force the main characters to have tension.
Late evil team plot.
The dub's bad lines and music.
Lisa Ortiz grinding her voice on a Gym Leader AND becoming the voice director? Ha ha, NO.
I could say more but I don't want to kill this season.
