Prison break showcases what sacrifices does a man make to save his brother from prison. As the story unfolds we get to know more interesting and engaging characters and the sheer suspense of how they are going to break out of prison is thrilling. The first season is 21 epsiodes and it is the best season of the series followed by season 2 which is also very good. The only problem of the show is that, the quality of the show degrades with every season. From a fantastic first season to a mediocre fourth season and now it is again back for an average fifth and sixth season. Overall it is worth a watch for the mindless entertainment it provides for more than three sessons.
