I like the work of Star Trek: Hidden Frontier, which includes Star Trek: Odyssey and some other stand-alone movies. Their technique is a little different. They green screen everything versus building sets. So the "production quality" is worse, especially in the early seasons. But they more than make up for that with interesting complex stories and usually good acting. It's set in 24th century timeframe, mostly focused on "Briar Patch" area from Star Trek: Insurrection. Very well written. I also got a kick out of watching "Keeping Up With the Cardassians". Not really a Star Trek story, so much as a "real-life" documentary, but it's fun.
