As viewers have come to expect from the filmmakers behind the project, the movie was indeed hilarious. The laughs abound all the way through, and there is, refreshingly, no one token dramatic scene that kind of brings you out of the humor of the movie. The casting was spot-on: forget what you know about him, Zac Efron was raunchy and completely right as frat president Teddy Sanders, and Dave Franco gave a great performance (as always) as frat vice-president Pete. Rogen and Byrne were so unbearably hilarious and had great chemistry, and even Ike Barinholtz and Craig Roberts shined in smaller roles. Speaking of smaller roles, I especially loved all the great cameos in the film: there are some unexpected treats from other frat boys of comedy, so to speak, and each one made me oh, so happy. Oh, and even the baby, played by twins Elise and Zoey Vargas, was great! The jokes definitely toed around and took great leaps over the proverbial line (the trailer reveals the baby mouthing a used condom, and that's just as horrific and gut-wrenching and disturbingly funny as you think it would be), and Stoller didn't hold back from anything inappropriate and horrible as long as it was funny (and it all is!, including maybe the least offensive use of the n-word by a white guy ever...), but that's just my kind of humor (although I personally thought there weren't as many dick jokes as promised and wanted more; I wonder what that says about me...). I loved it, and the guffaws from the rest of the audience seemed to indicate love, too.
But whatever. The movie is definitely hilarious, lewd, uproariously stupid, and filled with filth: it delivers what you expect from a Rogen/Goldberg movie, and ups the ante for a Stoller film. Go see Neighbors; you'll have a raucously fun time and won't regret it.
