Case in point: Babylon 5. The show's creator, J. Michael Straczynski, originally planned for a full 5 season run. But he was forced to cram the ending into season 4 because of uncertainty over the future of the show. Then season 5 was approved at the last moment - with most storylines already wrapped up. He had to create something for the next season, but it wasn't what he'd envisioned from the start.
