Ah yes, the part in Top Gun where that one guy I can't remember goes back in time because he accidentally nuked Vietnam... and the last Vietnamese miner swears revenge and blows up New Jersey.
Like it or not, the Star Trek reboot had a lot more subtlety and strength than pretty much anyone gives credit for. I could give a play-by-play of nods to original continuity, the oddly well-played Shatnerness of the lead actor, the way the movie plays with putting the cast of TOS in a TNG (or DS9)-type scenario, the way Kirk gets fleshed out in the alternate timeline where he doesn't have a father to look up to, the shit Spock went through on Vulcan, etc. But Abrams was above all making a TOS Trek movie. An above-average Trek movie at that. 1, 3, and 5 were nowhere near as good as this, and 2 pulled together almost entirely on the charisma of Ricardo Montalban. The rest were okay. It's because as a cinematic piece of entertainment, Star Trek can never be more than okay. It's part of what makes Trek Trek. There's always too much baggage from the series itself, too much focus on garbage technobabble that even infuriates fans. Star Trek is good, it just can't make a good movie. And yet, there were inexplicably 3 good movies! Why? Because the bad movies weren't bad, they just played too much like an episode of the show! And here's where Abrams delivers: he doesn't have or need the show as background, but if you pay attention, the movie is subtly steeped in lore and personality, undiluted Trek with the 60's-ness stripped away.
Also, let's talk about Avengers. And Disney by connection, and Lucas by connection. The Avengers was not given the Whedon treatment, if you will; it didn't become a campy mess that forgot what it was about halfway through. Why? Because Disney and Marvel HAD HIM BY THE BALLS and WOULD NOT LET HIM SCREW UP THEIR FRANCHISE. Disney will do exactly the same here, and Lucas has been included as a consultant, need we forget. He gave away his baby, but he still has visitation rights and isn't going to let its new parents turn it into a monster (prequel rant flame shield up). I repeat: J. J. Abrams isn't the only hand in this! Lucas is still on as a consultant, and Disney has too much stake in this to let anyone screw this up. They hired one of the best to write this thing, Michael Arndt.
You said in the beginning that you hoped you would be proven wrong. I say now it is very likely.
