depends really...
the first one was a good film, a nice all rounder, has character development, and a little pinch of gore and action sequences. While it's a typical, almost 'zombie' genre film, it still manages to tie in a decent storyline where the underlying theme seems to say internal human conflict surpasses even a greater force out there.
the second one was more of a night of the dead/dawn of the dead sort of film, little character development, just jumping straight into mass violence and gore, which they did pretty gd imo. Chopper scene was pretty gd lol.
