Good movie but not a #1 movie of all time

Rating: 6/10 (14 April 2020)

This is a good movie but it is far from being the best movie I have ever seen. The plot is ok but with many plot holes that I don't find really convincing. What do I mean by that? Well, the way that Andy dig the tunnel from his prison cell for years and that nobody noticed because it was behind a simple pretty girl poster.
This movie is probably among the first movies about life in prison like this but these scenes are now so cliche (prison rape, creepy guy approach in shower, corrupt officers, etc.) and to me they are so predictable. I like movies to be unpredictable but with this one I guessed everything that was about to happen.
It's just so unconvincing that he is able to run like that and to even be accompanied by Red later (like no one would follow Red to see if he takes them to Andy).
