It was a fun movie

but it made no sense that the prison never put him under surveillance and just left him all alone for such periods of time. I mean they didn't think he was actually getting out but they figured he was communicating someone with someone on the outside. They would have monitored him by video or with guards at his cell.

Also, if was a fun movie but actually being inside the prison made no sense. TOO many things could have gone wrong and there'd be nothing he could do about it, if they transferred him or watched him around the clock.
