I understand that this film may have been groundbreaking in its time, but this is simply a film review from someone in his 20's in 2021.
Another horror movie that has no believable characters. They all have stupidly simple motives with zero nuance. The movie relies fully on main characters making uncharacteristically poor decisions every step of the way. Just lazy, boring writing that wants to get to the killings and horror by any means.
I laughed once, and that was because of a really clever piece of special effects. The two stars are for the gory effects and a couple of excellent zombie performances. Everything else was boring. How am I supposed to enjoy a movie with a bunch of incongruent characters bumbling around? The dialogue was pretty lame too. Watch it for the special effects and expect nothing else cool or entertaining.
