I saw this film this week, it was handy that Hostel part 2 was still fresh in my mind. This film wasn't written or directed by Eli Roth like previous ones in the series. It also went straight to DVD upon release. Once you get a series of films you can usually expect the quality to go down and this isn't really an exception to that but it wasn't as bad as I was expecting it to be.
I can't say I enjoy the Hostel films because they are all pretty depraved and quite gruesome, this one being no exception. The story concerns a group of young men going on a Batchelor weekend to Las Vegas I think. It's all been set up by the Best Man, he arranges a party somewhere out of town with a couple of prostitutes. The next morning when they get back together one of them is missing. One of the prostitutes is also missing. You guessed it. They have become inhabitants of the Hostel. The hostel this time isn't set in Eastern Europe, disappointingly. It is instead set somewhere close to Las Vegas. The plot is very thin to be honest and it doesn't get much better, however the film is well paced and doesn't go on for any longer than it needs to. If you "enjoyed" others in the series, this one shares a number of the familiar tropes but it has slightly less quality than the others in the series. The first film is still the best.
