Watching it again and again
I feel this is one of those rare movie that just keep getting better the more I watch it. First time I watched it was decent, then with each subsequent view it kept getting better and better as more nuances that extend back and forth in the movie becomes more and more apparent. Now I think it is a classic worthy of its time. Heck, I didn't watch the extended trailer until after having watched the movie 4 times and it gaves me tears in the eyes.
It may have some flaws, but it is really well crafted and will be a movie I will always remember.
