Well, Star Wars 7 won't be good. It'll just be. Like The Hobbit films.
I disagree. Abrams doesn't really have the reputation for making overly long stuff no one really wants. Instead he's known for giving fanboys just enough to be excited and feel validated about, while being just safe enough that everyone else is nodding a little and saying "well that wasn't too bad."
In other words, we'll probably be getting Star Trek instead.
