To the Mod's I would merge this, I made this thread years ago, and I looked at this and was like this seems familiar lol.
Anyways I will repeat my old list, and add some new ones.
Quantum of Solace-Seeing that in theaters I did not like it at all. But on subsequent viewings, especially watching it back to back with Casino Royale made it so much better. Now I actually really enjoy the film. It has shortcomings but is still a great film.
The Mist-The first time I saw this I did not like it at all. But I bought it on Blu-ray, and since I don't understand why I did not like it. I watch it again and again and again.
Zodiac-Same for me, I thought it was boring as hell the first time I saw it, but now whenever I watch it, I'm tense and creeped out the entire time.
X2: X-Men United- For some reason I had a poor theater experience when I saw it opening night, but when I went with a friend the next day I was blown away, and since X2 is my third favorite comic film behind TDK and BB.
Old ones that are common for most were like Apocalypse Now, The Godfather, 2001, Blade Runner, all common ones where I had the same experience.
And one that I thought was good the first time I saw it but on subsequent viewings has become an absolute classic would be The Prestige.
EDIT:
I would also add Hulk 2003 in there. At first I hated this film for years, but now I watch it, and absolutely love it, very under-rated.
