Hmm. A couple things.
First of all, the list is misleading... it's not just sci-fi shows. It also includes fantasy shows, animated series, and superhero/comic book stuff.
Second, although the list itself is not bad... the order is highly debateable. And there are some odd omissions:
* Star Trek: Deep Space Nine (actually mentioned in the same page as B5 but no place on the list??)
* Farscape
* Red Dwarf
* Angel (they mentioned Buffy and Angel is just as good, if not better)
* Robotech/Macross
* Neon Genesis Evangelion
* Transformers G1 (they had the Jetsons...)
And if you are including stuff based on comic books, like Wonder Woman then you should also mention-
* The Incredible Hulk (live action)
* Batman: The Animated Series
* Justice League
* Smallville (possibly... at least it's better than Lois & Clark, imo)
* X-Men: TAS
Probably some other anime could go on there as well.
If they make a list like that, they need to be more specific about what they consider sci-fi. Or divide it up into categories...
