A bit of a bore, is 'J. Edgar'.
Leonardo DiCaprio puts in a very good performance as the titular character and his co-stars are all solid, but I just found the way that the story is told to be lacklustre. There aren't, at least for me, any memorable scenes and I wasn't invested in the plot at any point really. It's semi-watchable, but goes on for too long to be passably so.
It does, as noted, have a neat cast list, with Armie Hammer, Naomi Watts and Judi Dench, among others, involved behind DiCaprio. I think they all give their best, with any issues I have with this 2011 release being away from them. Two duds in a row to start the 2010s from Mr. Eastwood; in my humble opinion, of course.
