Pretty "trendy" and quirky movie, as you'd expect. Cera as the badass is really what steals the show here, and without this element, this would have been just your run-of-the-mill Juno-wannabe hipster movie. With it, it becomes actually quite entertaining, though it leaves you hoping Cera diversifies his character palette more often in the future. Regardless, this will keep your attention through to the end and entertain you fairly effectively, though it will also weird you out a little every now and then with its constant attempts at being hip. It's worth watching, though, especially if you liked Juno.
In a sentence:
Good acting from Cera through a decently interesting and quirky plot equals a pretty entertaining and light teen movie.
