Matt Singer at The Dissolve pretty much nails it:

Seven years. That’s how long it took for Seth Rogen to evolve from the pot-smoking dude who’s too immature to have a kid in Knocked Up to the sensible, responsible family man outraged at the immature, pot-smoking dudes from the frat next door in Neighbors. (Via.)

True! It's weird Zac Efron is playing a role that seems like Rogen should be playing. (Something else that's weird: Typing that sentence!) HOWEVER. Maybe I'm still coasting off the fumes of the surprisingly great This Is the End (which is heading back to theaters this weekend), or maybe it's just that director Nicholas Stoller (Forgetting Sarah Marshall, Get Him to the Greek, The Five-Year Engagement) has built up a whole lot of good will at this point, but if I were a betting man (I AM! BET ME!), I'd say Neighbors will probably be pretty fun. Because I mean, shit, that final joke of the trailer is right out of a Kevin James movie, and I still laughed.

Goddammit. Now I have to watch that Kevin James video. Walk with me on this dark path.
