I've seen "Breaking the Waves " twice already and have grown to love it.
The first time was in a theater: I recognized the concept von Trier was using and appreciated Emily Watson's performance, but wasn't sure exactly whether I liked it or not. The second time I saw it was on cable and I didn't have to think so much--I really liked it the second go-round.
It's been several years, so I think I might benefit from seeing it again.
