Definitely a very good movie, though I don't think it should be ranked as the best of all time by IMDb. Because of the nature of the IMDb's consensus voting I think it gets to the top because it's the most difficult movie to dislike, rather than one which might be better, but contain challenging elements which might cause some people to rate it lower. I don't want to sound too down on this film though because I do like it. It puts across its themes of hope and redemption well, it's got a great script, and great acting across the board. Some of the plot seems a little forced at times, but the movie does a very good job of allowing the viewer to sympathesis with Andy Dufresne and root for him to succeed.

Really good movie. But not necessarily the best movie ever. Watch it, but don't expect a masterpiece.

this must be the only movie where a banker is a cool guy
