I agree. I always thought that ROGER was the supposed 'main character,' I guess. Roger's story through Mark's lense, with Mimi as the leading lady, Mark as another leading character, and the rest being a part of an ensemble of supporting characters. I thought this should have been fleshed out in the movie, but sadly, the cuts didn't work that way.
But that's really my opinion...
Oh well. I still love the movie, and I think Adam did a fabulous job with what he had.
