Why Prison Break has to end

ABC has only recently announced the popular series Lost would be ending after three more 16-episode seasons – ample time, fans hope, to cleanly wrap up the convoluted story of the plane crash survivors. The series has been criticized for seemingly leading loyal views on.
For the producers of Prison Break, the same reasons apply. Fox released a statement not too long ago that the 4th season of the jailbreak series would be its last. In an interview here, Prison Break executive producer Zack Estrin revealed that they long had the feeling the series would be ended by Fox, and have subsequently adjusted the story so that they would have a good and solid ending when the time came. Estrin stated that to continue the story and stretch it would be “irresponsible”.
