With respect to number6's list above:
Absolutely, "City on the Edge of Forever" and "Cause and Effect" are great episodes, and I would count separately (i.e., as a meritorious comedy) ST: IV. But is anything else on this list really that enduring? "Time's Arrow" was as contrived as could be, and all that really sticks with me is the fairly convincing Mark Twain. And although "Tomorrow Is Yesterday" had many fine moments, the resolution of the story ("replacing" the Earth guys into their lives such that they didn't remember) never made much sense.
As for the new movie, I'm really starting to wish they hadn't bothered. Something I read elsewhere today made me realize what my reaction was; I'm paraphrasing here: "My wife saw the trailer and said that the movie Starship Troopers was more like the book than this film will be like Star Trek." My main hope is that Michael Giacchino will do a great job with the music, which can redeem a lot of bad scripting - for example, most Freiberger-era TOS episodes or Goldsmith's TMP music. (Trailers generally don't use music written for the final film. They often borrow from preexisting sources - I recall seeing a trailer or TV ad for Who Framed Roger Rabbit that made very effective use of Bernard Herrmann's North by Northwest fandango. Not to mention the legendary use of the song "If I Didn't Care" in the trailer for Blade Runner.)
