You say you watched the TOS episode "Who Mourns For Apollo." You should check this out. You will love the guest star!I agree JoKippe, you could tell that both DS9 and Voyager were getting a bit thin after a while. Anyway, one reason I wanted to see Enterprise was that I know that was the show that introduced the Undine. You encounter those guys rather frequently in Star Trek Online.
Speaking of Trek, I felt the first Abrams reboot movie was kind of mediocre, not bad but not great either. Shoot me though, but I really enjoyed Into Darkness. To my mind the chemistry between Kirk, Spock, and Bones was better in the second than in the first.
One more Trek blurb: In going through TOS second season remasters, just watched Metamorphosis, and I'd forgotten what a nice, touching, sentimental story that was. It isn't often that sentimental/romantic stories work very well in scifi, and that little gem was one of the better examples.
I thought DS9 to the the superior 'Trek. Not being able to fly off to the next week meant problems didn't go away as easy as they did for the ship based episodes.
Enterprise had everything except good scripts. They had a wonderful opportunity to see the Feds meet, say, the Klingons for the first time but instead they just had one running about on Earth on a farm in the first episode. That third season Xindi story arc was so very lame it killed the show. I really liked Jolene Blalok as well.
