I just finished re-watching Babylon 5 after not having seen it for many years--brilliant, compelling and not at all dated! In many cases, the level of character development meets, and occasionally surpasses that which we typically saw in the various Trek incarnations. Good, solid story arc and overall top-flight science-fiction. My wife watched it with me (her first time) and, although she squirmed through the first season, by the second she was thoroughly hooked.
Makes me wonder what would have become of Crusade if Strazinski and Turner had been able to come to terms?
