I found this episode to be slightly less entertaining thatn the others. The storyline was definitely great - an inncent may turn guilty after all this time. Also, the fact that there is an innocent man in Alcatraz made this a very interesting storyline to follow.
However, there really wasn't too much drama or suspense hthroughout the episode, and it was not as epic as most of the other episodes.
Still loving this show, and I hope the next one is better! :)
