I actually liked O'Hare's attitude and demeanor as the boss of B5, didn't realize there was so much dislike of him playing that character during the first run.

The creator/showrunner JMS was a friend of that actor Michael O’Hare, and paid for a lot of his living expenses and psychological care after leaving the show. JMS offered to put the show on hold entirely until O’Hare felt well enough to take up the role again, but O’Hare was concerned that would hurt the show’s chances of lasting beyond season 1, so he stepped aside voluntarily. JMS never said a word of this until O’Hare’s death in 2012.

:rat-salute: To JMS, as a pretty awesome friend.
