This is one of those 80s films / Stallone films that have been forgotten with time and like many of his films, they deserve a rewatch as both critics and viewers alike have been pretty harsh on some of his films during that period. As it stands, Lock Up is a pretty good movie as it has good performances all round and the subject of prison is very interesting in the way that it has been portrayed in the film.

It definitely has a few negatives as the last 30 minutes are extremely rushed with it almost feeling a little anti-climatic and also some of the things that happen in the prison/prison system are a little bit unrealistic. But it is definitely worth a watch as Stallone gives a great performance and the rest of the at do a pretty good job as well and I can also see where some of the inspiration for Escape Plan came from with this film.

If you like Stallone films then you are definitely gonna like this film and if you like films about Prison then definitely give it a try, but don't go in expecting Escape from Alcatraz.
