1. Star Trek: The Next Generation and Deep Space 9, were pretty all-right. In fact, the last season of DS9 was terrific. But I hate how they make pseudo-scientific leaps of logic each episode at the crisis moment. Never liked the original series at all, cept for the tribbles. Got to love the tribbles. Oh, and the ST II: Wrath of Khan movie was incredible stuff. I recommend it to even non-scifi fans.
2. Star Wars is very derivative, but the first three movies to come out were still great. Episode One was a hour-long toy commercial. I fell in love with the TIE Fighter and X-Wing games, though. Wow.
3. Their monetarily poor but vastly superior rival,
Babylon 5, owns both their asses (IMHO, of course ). Skip the boring pilot and tune in about halfway into season one and you'll be sucked right in.
Back to the question: Of Star Trek and Star Wars, Star Wars is more adept at pulling at my heartstrings. Don't know about "better".
Okay, I have a lot of time on my hands tonight. I absolutely refuse to do anything worthwhile until I move onto cable later this month!
