The Crow-I originally thought it was too dark when I watched it the first time. Brandon Lee's performance is charasmatically phenomenal, and brought much more light to the "dark" scenes that were taking place. I love the film now that I've viewed it several more times.
Blade Runner-Didn't grasp the story too much, I thought it was an overrated film at first despite the fact I loved Harrison Ford's movies. Watched the Final Cut, Loved it!
Indiana Jones and the Kingdom of the Crystal Skull-Very disappointed with the theatre viewing like so many others. Watched it several times after it was released. There were things I appreciated more than the first time I watched it. Still my least favorite Indiana Jones film.
Iron Man- I thought the film had some flaws, or at least the way I originally saw it. But after watching it several times, I had a second opinion, you gotta love Robert Downey, Jr.!
Secret Window-I originally thought the movie was a BOMB when going to see it in theatres, but after viewing it a few times on DVD, you'll clearly identify with Johnny Depp in this role. It's quite like Johnny. Great acting on his behalf, the dialogue is great too, so I really enjoyed it thereafter.
Shrek- Didn't care for the film when I saw it in theatres in 2001. But when it hit DVD I watched it quite a few times, pointing out several of it's funny scenes, I kinda enjoyed it! so I had to love it by then.
