This film just shows you how Sam should have just shot Ginger since the beginning. Good film and a good ending.
The movie has a pretty simple plot, but the actors, camera work and scenery make it interesting to watch. I'm really glad it had a happy ending for the good guy for once, too many crime dramas end differently.
It started with a lot of narration explaining the context. Might be a bit tedious for the first few minutes but as the movie building up its tense I was getting used to it. This is a very long movie (3 hours) and there are lots of moments lumped into the movie, but it all tied up nicely, with some events unsuspectingly leading to another event.
I watched this after Wolf of Wall Street, and I feel a similar vibe (though obviously with many differences): a quest to power, wealth, stardom--and how the guy trying to maintain it ended up with losing everything. The last scene nailed it best, evoking how all his greed resulted in nothing and he has it enough with "that's that".
