Prison

After Charles Forsyth was sent to the electric chair for a crime he didn't commit, he forever haunts the prison where he was executed. Flash forward several years when the prison is reopened, under the control of its new warden Eaton Sharpe, a former security guard who framed Charlie. When prisoners are ordered to break down the wall to the execution room, they unknowingly release the angry spirit of Charles Forsyth, a powerful being distributing his murderous rage to all, leading up to the Warden himself.
"PRISON" (1987) can be found in its entirety on YouTube, at least in the United States. It's fun due to the still impressive special effects, beautifully lit set, and fantastic filming location, but ultimately forgettable due to lack of character arcs and proper backstories, a stereotypical haunting method, and somewhat predictable deaths. Once someone wanders off, you know they dead.
Also, it was a teeny bit racist. Not entirely, but pulls a minor scene that could be seen as questionable in modern times.
Overall, fun movie where real life logic doesn't apply. Sit back, grab a popcorn, and ignore the fact that someone is being electrocuted wrong in a gas chamber.
Also, Viggo Mortenson is in it. So yeah. It's free. It's 80's. It's pulpy fun. Go watch it if you like that kind of stuff.
