In season one, I thought there will be only two seasons. After season two, I knew at least three. Hopefully, there is no season four.
I'm not sure but I feel like they are stretching it too long with all these seasons. I want to see what happens already.
Yea a season 3 is enough, otherwise it will look way too unreal for some prison fugitives to avoid the cops so many times.
I think season 3 would be the end, since i can't really think what they would do except keep running, and the ideas might start to run out.
I love Prison Break so I hope it continues but there is always the danger that it can get over done. Shows like The O.C, Buffy, went on too long and the final series let them down.
