Heh, Sheridan was by far and large my favourite character on the show. But then, I only really got into Babylon 5 once the story picked up more in Season 2. A lot of Season 1 was set-up work for things to come and the pacing was often too slow for me. And none of the characters really clicked for me back then other than G`Kar and Londo.

I did enjoy Sinclair`s return in the time-travel episode. But Michael O`Hare was having mental health problems so he asked to leave the show and get help. I can always make a transition like that easier if it was the actor`s choice and not a question of the writer wanting to replace them.
