ok firstly and if your not a fan of the whole low budget horror genre then do not bother with this. you really need to be a fan to get the gag. the move is basically about snakes . on a train. lots of them. there is an ancient curse involved and a crazy ending which i wont spoil. the gore effect are full on and real icky. but the movie is mainly one big gory gag about snakes scaring the hell out of a bunch of people trapped on a train. the suspense is built up well and there are some memorable and well composed scenes. some of the acting is a bit hammy (watch for the surf dudes) but thats not really the point. give this movie a go. know what to expect and you wont regret it.
