In defense of this movie
A lot of people (at least the ones who have posted) seem to have not liked this movie. But the major complaints I've read were the exact same reasons I enjoyed "Roger Dodger". The two main complaints are the parts of the movie I felt made it so good.
The use of all hand-held cameras was shaky, true. But this is what made it feel quasi-voyeristic. It seemed like the audience was just following along with two guys running around New York. The loose and unpredictable framing is the same way a normal person sees the world.
The ending left a lot of people wanting closure and whatnot. But the fact that the movie cuts off at a seemingly crucial moment goes along with the feeling that we are just there having a glimpse at the character's life. Until death, all our stories continue, and the fact that R.D. ends without final resolution reflects this.
The entire feel of the movie, for me, was that we were simply outside observers who had a chance to see a part of a couple guys' lives. There are events before we start watching (the movie picks up mid-conversation with Roger's theory of man's role in the species) and we end mid-conversation between Nick and Angela.
So anyway, I just thought someone should stick up for this movie since it seems most people didn't like it. Tell me what ya think.
