This is Thor. He has a hammer.
I'm going to spoil the movie for you now. Thor is about a bad-ass dude/demi-god named Thor. He has an awesome hammer which he uses to smash things (Ice Giants, walls, etc.). His hammer is taken from him and he must get it back, so that he may smash things with it.
And that is the entire plot of the movie, though there is also a love interest. After all, what's the point in being a large man with an epic hammer if you don't have a girl to show it off to?
This movie understands everything that is important about life and is indeed a celebration of living. Too many movies these days try to burden the viewer with complexity and layers of meaning, perhaps because the writers consider that complexity and depth are the same thing when they rarely are. It is the simplicity of the movie that makes it awesome, you have an epic character with a simple but vital purpose and he relentlessly pursues his goal to the end. What better message could be put in a movie?
The simplicity of the main character is also a key part of the movie's appeal. Thor (the character) is awesome. That is basically his entire description. There's no need to discuss his beliefs, his attitude, his desires and other nonsense, because he can be described with just a single word. In the context of our ordinary world he appears odd rather than awesome as he clearly doesn't fit in but you can see by his own bearing that he knows he is awesome and the opinions and reactions of everyone around him are irrelevant to his knowing. The definition of personal integrity right there.
If I were to rate this movie on a scale of 1 to awesome, it would be 12.37 multiplied by the square root of epic. Go see this movie.
