Other than some funny moments (mainly thanks to Franco) and interesting chemistry between all the leads - this was the same ol' tiresome stuff as the last twenty comedies to hit theatres this year. Same boring formula, different bass-heavy mixtape soundtrack.
Laugh-out-loud funny, featuring good performances all around. This film has plenty of things to admire - an atypical female lead in Rose Byrne, some typical Rogen homoeroticism, and a fast-paced script - and will leave most any audience satisfied.
Normally it would only get 2 stars. There's no protagonist but the inevitable death by old age of youth. The baby fears speaking, just as the frat bro fears post-college life and the 30-year-old fears the next year. Like the flowers in the vase, we all perish after beauty fades. ALSO THERE WAS TITTIES! And that Zac Efron? This is me watching him!: http://i.imgur.com/enaVS9S.gif
So it gets 3 stars. Still kinda bad.
