Seeing that there was a topic asking the exact opposite of this question, I was curious; what films are worse on subsequent viewings for you?
For me, it has to be the original Avengers. Every time I watch it, something about it grates on me a little bit more which brings my opinion of it down. Part of it has to do with the dialogue; I don't like the "quippy" way that Whedon writes characters, especially when they seldom speak that way in reality.
