The acting by Leonardo DiCaprio was stunningly amazing as he brought the whole drama to realism. Perhaps, he could even win some awards. DiCaprio and his co-star Armie Hammer was able to pull off it off with chemistry. Their portrayal was pretty good.
The narration, order of the scenes, visual effects were sufficient to support the story. Although the make up is a bit flawed especially with Clyde Tolson's character.
Overall, the movie was interesting to watch. I found myself immersed into the show curious about how his life went on. However, it may not be for everyone as we saw quite a number of audience walk out during the show.
Watch J. Edgar!
