I'd only seen a few positive reviews for the film and I think generally overall it's about 50/50 for critics, so I thought going into it that if it's not great I wouldn't be shocked and vice versa.
I was pleasantly suprised, I thought it was a really well done film, the costume designs and the whole setting was convincing, from 1920s America all the way up to the 60s and 70s, the lighting was a little dark but generally suited the mood of the scenes.
Leonardo DiCaprio is always on his A game, he's clearly one of the best actors working today and has been for probably his whole career and in this he's no different, stunning performance. I wasn't a fan of Armie Hammer before this but I think this may have helped me come around to him, and aside from the badly done aging makeup he was very good in this as well.
I don't really know much about J Edgar Hoover so it could be completely inaccurate and I wouldn't know but it felt genuine and was a gripping story from start to finish, the guy who wrote it, Dustin Lance Black also wrote Milk
which was one of my favourite recent films so I'm glad he did another good job on this.
Although Clint Eastwood is a bit hit and miss when it comes to directing, he definitely is dead on here and it was a really impressive piece of directing, and considering he had to try to condense 48 years of a mans life into just over two hours, I think he was spot on.
I was really glad that the Eastwood, DiCaprio pairing worked so well in my opinion, despite the negative reviews I'd seen, and I think regardless of what you've read it's definitely worth seeing if just for DiCaprio's performance.
