Review: The movie is basically a boring string of appalling clichés which do not offer a real cross-cultural insight. The Middle Eastern leg of the journey is described in a particularly irritating way: there obviously are mud brick villages, dirt tracks in the middle of the desert, women clad in black robes and belly dancers. I wonder how camels and date palm trees were missing from the whole picture. The personality of the two main characters is very clumsily sketched and many situations are hardly credible. The original idea might have been interesting, but at the end of the day if you are looking for cultural insight, you should skip this movie. Question: is it a positive review?

no

Review: Prison is not often brought up during conversations about the best eighties horror films, and there's a good reason for that because it's not one of the best...but as you delve past the classic films that the decade had to offer, this is certainly among the best of the lesser known/smaller films. The film does have some connection to blockbusters; for a start it's an early directorial effort for Renny Harlin; the capable director behind a number of action films including Die Hard 2, Cliffhanger and Deep Blue Sea; and secondly we have an early role for Lord of the Rings star Viggo Mortensen. The film is not exactly original but the plot line is interesting. We focus on a prison that has been reopened after a number of years. This was the prison where a man named Charles Forsyth was sent to the electric chair after being framed by the prison's governor. Naturally, the spirit of the dead man is not resting in peace; and when the old execution room is reopened, the spirit of the dead convict escapes for vengeance.The film is not exactly The Shawshank Redemption, but it does take care to build up its various characters and while the main point of the film is always the horror, the prison drama behind it all does make for an interesting base. This is a good job too because other than the basic premise, the film doesn't really have a 'plot' to go from and we solely rely on the interaction between the characters to keep things interesting. The horror featured in the film is at times grotesque but it's never over the top, which might actually be the reason why this film is seldom remembered, being released in a decade of excess. The murders themselves are rather good and imaginative, however, and provide some major highlights. As the film goes on, we start to delve more into the back-story of the vengeful convict's ghost and while it's fairly interesting, some things about it don't make sense and it drags the film down a little. Still, everything boils down to an exciting climax and overall I have to say that Prison is a film well worth tracking down. Question: is it a negative review?
