I wanted the living dead action to start. Once it did the movie got much better. The zombies all looked pretty good, and their carnage was decently done. The cramped setting of the plane made it more interesting as the characters had to go right through them to get anywhere. There are a couple of cool deaths, and the ending was perfect for this film.
The directing was good, the make-up was good, the effects were good, the acting wasn't too horrible and the script was fairly smart and funny in spots. I'm rating all this on the straight-to-video level, this film certainly isn't going to hold up with the greats, but for a low budget zombie movie, you could do a lot worse.
