Anyone who reads my stuff is quite aware of the fact that I am pretty harsh on Leonardo DiCaprio and I just want to play nice for a bit and say that unlike his other roles, I actually feel as though he fits in perfectly here.
I don't think that Inception really needs much of an introduction but if you were living in a cave in 2010 and somehow managed to be one of the 2 or 3 people on the planet that hasn't seen this movie, you need to find a way to watch it immediately. I have seen this film 20 times or so and would gladly do so again. I mean, it is just a perfect movie because it has a completely original story, the action is just perfect, and all the actors were chosen just perfectly.
I have to admit that i was a little apprehensive about Joseph Gordan-Levitt being in it but he actually nailed his role as Arthur in the film as well.
So why do I feel that Leo is a believable adult in this whereas I don't find him convincing as an adult human in most of his movies? It is simple really, because his adult life is very atypical in Inception. Sure there is the mention of the wife and kids but for the most part that is not the focus of the film. The focus is the fact that he the "leader" of a group of people that steal information by entering dreams (as I am sure you are aware - sorry if you didn't know that but it is revealed in the first few minutes of the movie anyway.)
[source](https://swaleff.files.wordpress.com/2010/07/inception-movie.jpg) This is such a far-fetched position for anyone to find themselves in that DiCaprio's boy-ish-ness doesn't get in the way of him being capable of being a convincing person in a leadership role. This is his major failure in any film where he has a house, or a wife, or anything "normal" including a normal job. This is similar to the layout of his role in Blood Diamond, which is also an epic film that resulted in an Academy Award nomination that I feel he truly deserved to win (he didn't.)
This isn't really a film review so much as an admission that I realize that Leo is a talented actor but I don't think he is fantastic in a vast majority of his films. Normally I say that most of Leo's films would have been better if they instead had been Matt Damon films. I don't believe that to be the case here. Leo was the perfect choice for the role of Dom Cobb and I can't really imagine anything that he could have done better in his performance.
So there you have it! I'm not always hating on Leo, but I do call 'em like I see 'em.
