bro I'm watchin' the final season of Voyager. Let's both go into Enterprise next. :3

Have you exhausted all the other Star Trek variations that pique your interest? (Except for the first few seasons of Enterprise, which should be burned)

No, much of TNG was made in the stand-alone episode way. I think the plot arcs begin in the... fifth season? I'm not sure, but it's pretty far in. TNG improves by a lot in the fourth season, and I really don't know much about the other series. The new movie is fun, but kind of light on actual Star Trekkiness. More of an action movie set in the Trek universe than an actual Star Trek movie. But movies being what they are- a self-contained three-hour plot line, I doubt you'd find what you're looking for.

I like the complex long-reaching arcs, too, but there's definitely something to some of the episodes in TNG. In one episode, for instance, Picard is captured as a Cardassian prisoner of war and the whole episode is torture and interrogation focused entirely on breaking Picard by any force or temptation possible; in another, Riker switches between a reality where he's a mental patient similar to Sisko's adventures in the early twentieth century (less the religious parts). These are self-contained 40-minute stories, but they're still very interesting. They're less sophisticated in the way that the Twilight Zone is less sophisticated, but that doesn't mean they're bad.

I will agree with liviconnor, though: You can feel free to forget the episodes where Riker doesn't have a beard, though. And, for the most part, though, it sounds like you want Enterprise, which is better about long-reaching arcs, especially the later seasons.
