I just finished re-watching B5 a couple of weeks ago. It's one of my favorite sci-fi shows of all time. I have to admit, watching it again after the revelation that Michael O'Hare was written out of the show due to mental illness puts the whole thing in a very different light. The introduction of Bruce Boxleitner in the first episode of the second season always felt a bit weird, and now the reason is clear. It's hard not to imagine how it could have been, as a lot of things in the story would have been much stronger if Sinclair had remained the commander of B5 until he went back in time (which I imagine would have happened later in the series). A whole bunch of major plot events in the later seasons would have made more sense with Sinclair, foreshadowing in the first season had to be re-done in the second season in order to fit Sheridan into the story. It's especially apparent since Sheridan is IMHO one of the weaker characters in the series. Most of the actors grow into their roles, but Boxleitner's Sheridan never seems to get comfortable. And of course, the pacing gets really weird at the start of the fourth season. They race to finish the shadow war plotline in the first few episodes, but I suspect that was supposed to last the whole season. Then they have to power through the earth civil war which really was supposed to be fleshed out better before kicking into high gear. B5 is a great show. If you haven't seen it, you should. But man, I'd like to see the B5 that could have been, where Sinclair was the commander and the writers had time to flesh out the end of the shadow war and earth civil war storylines properly.
