Voyager is horrible and really what killed star trek
DS9 is for the most part boring and tedious to sit through
TNG and TOS are on equal ground with me. most fans of one seem to dislike the other. I love these shows more than anything ever on tv.
Enterprise wasn't that bad. It made a lot of mistakes, but it was the first show that had the right spirit of star trek and focus on fun exploration since TNG.
the abrams movie was god awful. I don't mind that people like it, but anyone who thinks it was deep or intelligent is an idiot.
