Worst movie I have ever seen in my entire life. I will never ever rent this movie ever again, zombies who turn into aliens than back in to humans? come on now. I honestly cannot not believe how STUPID this movie was, like really? They spent more time doing the front cover graphics than anything else! Bad acting, bad director, bad everything. This looks like a movie kids from a local high school made, wait there's would probably be better. I don't recommended anyone to watch this movie, I don't think this should have even BEEN a movie, it's just terrible. The blood, graphics, aliens, zombies, how they turn, killer fish? Giant grasshopper? STUPID. It makes me mad how stupid of a movie this is.

This movie has an interesting concept, and it must have had a decent budget. The special effects are well-done, the story unravels well and is executed in an interesting way. The acting is not too impressive, but the actors do seem to be having fun with it and you get the impression it could have been a lot better if that was the intention. This is something of a shame, as the movie would have been more immersive if it had something of a more serious tone, but at the same time this playful tone is consistent throughout the movie.The odd thing is it at times does nail this serious tone, and even the acting would have been entirely forgivable if it had not been for one major detail: The Music. The Music for Undead is by far the worst music I have ever, in my entire life, out of all the movies I have ever watched, in the history of the universe, had the misfortune of being exposed to. Have you ever wondered what happened to the people who used to make silly orchestra music for the myriad slapstick comedies of the 60s and 70s? Look no further, apparently they moved to Australia and got involved in horror movies.It's a damned shame. I was able to make it about halfway through the movie until I had to turn it off, as the music became too annoying to sit through. The entire flick becomes a vision of what it could have been, rather than what it actually is. A shameful waste of what otherwise has all the makings of a brilliant zombie slasher.

As horror/sci-fi movies go, this is not one of the best. It is, however, pretty fun. Clearly inspired by some of the earlier Peter Jackson work, Undead features zombies, aliens, crazy people with guns, stupid people with guns, alpha male and alpha female and lots of blood. This is the good part.The bad part is that most of the actors involved are playing like they are having fun, but can't really act. Also, for a 2003 movie I expected slightly better special effects. The script was interesting enough, even if a bit confusing at times, but the biggest failure of the film was its inability to choose between comedy, horror and sci-fi. I don't doubt that reality has a bit of both, but in Undead, the transition just didn't work.Bottom line: I did watch the movie as it was done by the same people that made DayBreakers, which had an awesome 10 minutes start. Unfortunately, it's about the same amount of time this movie has that is really interesting, the rest being average, at best.

Actually, it completely sucks. I've watched thousands of movies, even half of the bottom 100 list. And 99,9% of these movies I could watch till the end. However, this was one of the VERY VERY few I had to turn it off after +/- 20 minutes because it was so VERY VERY bad.Characters are as flat as pancakes and really annoying. Zombies are as slow as snails, but yet they can punch through heads in less than 0,1 second when someone is standing in front of them. That reminds me of another question: how can they punch through heads so easily, were they suddenly given some kind of superstrength in their arms? I don't know why there are people who say this is a definite 'must-see', because it really isn't. It REALLY sucks (also in its genre), so you'd better avoid it, even if you like zombiemovies.
