B5 season 5? An interesting choice. It's been quite a few years since I've seen Babylon 5, but as I recall season 5 suffered from JMS having to write a lot of his season 5 material into season 4, as he didn't know if the show would be renewed. As a result season 5 ended up being quite lopsided, with storylines like the telepath arc dragging out longer than they should have been. I think B5 was at its peak somewhere in seasons 2, 3 and 4.
