Haha we'll see. I watched the preview in front of the Hobbit, and, well... I wasn't offended? :lol I'd say this:
is my biggest problem with Abrams' movies. He can't pace a story to save his life. It's like... no one wants a 2 hour orgasm. You need the foreplay before the climax otherwise it just gets tedious like half an hour in. With Abrams, the whole is always less than the sum of its parts.
People like to complain that the opening act of a New Hope is boring, but people forget that the movie would fundamentally not work without those scenes (dat Binary Sunset). Similarly, the training scenes with Yoda (though I don't think anyone complains about that shit because those scenes are great). When characters grow, they need to earn that shit.
