Ever finish a game, think about how awesome it is and then ten minutes later change your mind? (Gears of War 3 will be my example)

Very often, in hyped games.
Metroid: Other M, I thought it was gonna revolutionize Metroid.
SMG2: I said it was the best Wii game, and I cannot replay it again without getting bored in 3 minutes.

I think those were the most notable ones.
