Saw this;last with the bride and two of our friends.
1. Phoenix should get an Oscar for this. Out, friggin' standing performance. He may be a screwball twinkie in real life, but the boy can act.
2. Liked the music and how it was placed in the film.
3. Outstanding camera work. The framing of the Joker in a number of sequences really magnified the feel.
4. The remainder of the stuff was a "no" for three out of four of us.
It was difficult for me to get over (in fact, I didn't) the utter destruction of the canon, and how it would impact everything else from the end of the movie until the Batman battles. These weren't little quirky differences.
We walked out of the theater with a depressed, "why" kind of attitude. It didn't connect in any way with us. The three of us pretty much agreed that it was a well made film that gave us little more than a "so what" feel.
2 out of 5 stars for us, the two of the rating being for points 1-3 above.
Glad I saw it, though. Phoenix is simply amazing.
