This movie, although graphic, is a very good rendition of what zombie movies should be like. The overtones of helping others through whatever happens can come as a good change in the newer horror movies that put sex at the forefront. Now although this movie is a good one, and the action scenes can get everyone on the edge of their seat there are a three main parts that require a mature personality especially at the younger ages. The first and most obvious is the full male nudity near the beginning of the film. It is a short scene that really sets a symbolic tone, but for the sensitive beware. Second is the first third of the movie is really dark. Zombies are everywhere, running away through sewers, having to put a bullet in some guys head to stop him from becoming a zombie. It can be a bit much for a squeamish viewer to handle. Finally the last part of the movie revolves around the plans to rape the two female protagonists. Note, this is not actually done and it is not said directly "I am going to rape them", but for an older viewer it is more apparent. This is of course balanced out by the surviving male protagonist rescuing them emphasizing the main message of the film. Overall a great movie, but make sure the younger viewers are more able to cope with the violence.
