What I'm getting from the comments is that these days I'm just a credulous fool and I like everything.
What I used to do when I didn't like something, was I would subconsciously sour grapes it into believing it wasn't that good and give myself an undeserved sense of superiority.
Like when I saw Sin City while in a bad mood, or felt like my subculture was being popularized in Tron Legacy. In those cases it really was just me.
