but the original version of this pilot was weak.
The original score was some awful synthesizer music that was painful to hear. They also had a bizarre tour through an alien zoo with muppets, and some fairly incoherent plot points.
Now, probably if you've seen this, you saw the "Special Edition" version they did for TNT, where JMS was allowed to tweak the special effects, put back in scenes PTEN made him take out, take other things out that contradicted what we would later see in the series. (For instance, all mention of G'Kar's wife vanish in the new version.) They severely changed the appearance and even the concepts of the aliens. (For instance, initially, the Minbari were supposed to be hermaphrodites, neither male nor female. They decided that Mira Furlan was better treated as all woman!) A few plot points are never reconciled, like how could you poison Kosh, who was essentially an immortal being of pure energy. Well, if you are an obsessive enough fan to notice, they've already got you hooked, so who cares? Part of the problem was a weak cast. Tamilyn Tomita, Johnny Sekka and Blair Brown were all replaced by the time the series went into full production. Patricia Tallman was also written out but brought back later. Michael O'Hare was a weak actor, and they sacked him by the end of season one.
