That's exactly how I feel about J. Edgar. I feel that Leo, as always, put 100% into the role - I thought his performance was fantastic, but I just didn't like how the story flowed. I enjoyed it the first time I watched it in the cinema (although I found it "choppy" and I'm not a big fan of movies with a lot of narration) but now that it's been released I find myself struggling to watch it all the way through again without stopping and going back to it, to be honest.
I keep forgetting about this thread I'm going to have to remember to come in here more often.
