I didn't bring up MI because I don't find it relevant. The film he worked on didn't do particularly well, and while it established the tone and a lot of the ideas for the future entries, it's not like other films in the franchise didn't do likewise. We see elements of Brad Bird's MI entry as well, and that film has the benefit of also being more successful at the box offfice.Into Darkness did quite well, too, those two Star Trek films are the best grossing of the franchise. The franchise simply never had the appeal he gave them prior. I also wouldn't cede MI III to you, it arguably wouldn't be what it is today without Abrams rebooting it, you can cite the box office but that'd be as disingenuous as pointing to Batman Begins' box office which was more humble than you'd probably realize, the box office doesn't tell the whole story, if it did MI III would probably be more like II which was a huge blockbuster, we'd have more slow motion doves flying by the heroes as they dive and shoot and shit. A lot of times you can look at how a film opens as a mix of how people felt about the prior entry and how well marketed it was, people like the first Mission Impossible, so 2 opens huge, they hated 2 so 3 opens soft, they loved 3 so Ghost Protocol absolutely kills it (III did better on home video than GP, in fact it may have the strongest home video performance of the franchise, no data for 1 and 2 they were prior to such things being tabulated at least on the sites I use). Speaking of Star Trek was an ABSOLUTE MONSTER on video adding nearly 200 million more to its grosses (about the same amount The Force Awakens has sold on video, no joke). You can call it primed but the performances are out of the ordinary, keep in mind it had been two decades since A New Hope when Phantom Menace came out and its huge box office take was only slightly more than A New Hope and that's WITHOUT ADJUSTING FOR INFLATION. Being big might be expected but JJ Abrams absolutely blew the roof off expectations.
I would also argue that again, the box office was primed for a major debut for star wars, as Abrams was continuing the franchise, not regressing into a prequel. Add a long more advanced and sophiscated distribution chains, and I'm not suprised it did better. Like I said, he has great timing, but his record speaks for itself. Great debuts
