I wish there were more episodes of ENT.
The last 2 seasons were terrific. I'll never get why people act like modern Trek deserved to be cancelled, it was doing great towards the end.
While I also enjoyed the last two seasons of ENT, the problem was it was the first two. I don't think many people stuck around to get to the good stuff.
As for second favorite series, it would be TNG. For a long time TNG was #1, but the Dominion War arc put DS9 over the top for me. I also agree with the poster who said TOS has more alike with DS9 than many think. I thought DS9 was the true inheritor to TOS in terms of how it handled social issues and characters.
ENT (only because of the last two seasons)
