As for the worst, definitely when Plasma kicks Munna. It's boring, it's useless, nobody cares about Munna, and for someone who has played through the start of the game about 20 times to get extra Victini's and can't skip that point, it just sucks. Plus the fact that Munna has to suffer, of course. Oh yeah, and I also kept getting confused by whether Ghetsis was actually there or an illusion.
