I just saw El Mariachi and Desperados, both were pretty decent. I liked the first one the most, there is a great scene in the beginning when he wants to work as a musician in a bar and the bartender says that he already has music and a guy starts playing his synthesizer.
The reason that I'm watching this many movies right now is that I'm in school all day rendering, exporting and burning the first version of my own movie (my graduation project). I'm soon finished with it though.
