Renny Harlin's Prison is another one of those obscure films that didn't find an audience immediately when it was released, but because of the word-of-mouth on the film and the constant bootlegging, the film managed to snag a small base of fans. Outside of franchise sequels, I'm going to go out on a limb and say that Prison is possibly Renny Harlin's best film. He's a talented director, has a keen visual sense, and directs the hell out his movies, but the story details in his films are always hazy and performances don't feel all that genuine. His movies are fun, which is the best way to describe them, but they aren't much more beyond that. I'd say that Prison is a little more than just fun and tries to do something a bit more story and character-driven. It has a strong cast, including an early leading role by Viggo Mortenson, a pretty well-laid out story, a bevy of impressive visuals and great special effects. It's been lost in obscurity for years, but now people can finally get to see what Renny was trying to do with the film. After all, it did more or less get him the job of directing A Nightmare on Elm Street 4: The Dream Master, which was his first big break.
