This movie is incredibly predictable after about 20-30 minutes in, and it's shaky camera and annoying 'different-backs-of-the-head+shakycam' shots, while they make sense, just made me feel sick to my stomach while watching the film. Still, I guess what draws the movie is the script and all the deep little metaphores in it. It's not a very engrosing movie, because I started coming up with a bunch of different titles for the film and duing filmic studies on the film during the whole thing to keep myself ocupied at boring parts, but on the metaphoric level, it's great. The movie could basically be called "The Mortal" but that wouldn't fly, and the song 'One Trick Pony' at the end of the film is probably the coolest part of the whole film.
What you need to do in order to get the full effect of the film is to think about all the metaphors that present themselves as the film progresses. Such ones such as the evolution of 'The American Dream', what it means to be culturally immortal in a mortal's life, what it's like to be a dying breed and what it means to be a constructed hero. If 300 didn't make you want to go to the gym, this film will for sure.
I'm my own breed of eccentric.
