I started watching TOS again for the first time after 20 years, and was surprisingly entertained (The "complete" versions of the episodes plus the clean-up and CGI added in make them seem brand new). In fact, I enjoyed TOS more than I did any of the 90s shows. The last good Trek movie was 6, which was an OK send-off/capstone). For all it's flaws, Wrath of Kahn still holds up amazingly well.
Did JJA bring trek back? Well, yes. Did he do it well? Meh. Number One mistake: Kurtzman and Orci writing team.
As for casting, Bones was the only character that they got right. Not only that, they had a decent explanation and update for the nick-name. Everything else--wrong. From start to finish, wrong. Completely and utterly wrong. The only way it can be enjoyable is if you are able to completely turn off your brain and not think about the movie at all. The second you start to think, JJA Trek falls apart.
Next Gen: OK, but lacked any sense of exploring. There was no frontier: it was Trek the Minivan Generation
DS9: everyone kept telling me it was as good as Babylon5. After 3 seasons, I gave up. Most of it was just awful
Voyager: well, they were exploring all new territory, but no one in that quadrant can figure out how to harvest comets for water? And a ship full of explorers whining that they want to go home? Several horrible characters given way too much time.
Enterprise: The good episodes were good. The bad episodes were painful. Way too hit-or-miss with script quality. Season 3 was horrid. Changed theme song was even worse.
