In the big-screen version of Rachel Cohn and David Levithan's popular young adult novel, two high-school seniors fall in love over the course of one eventful evening. A straight bass player in a queercore band, Nick (Juno's Michael Cera) has just been dumped by the two-timing Tris (Alexis Dziena). He's committed to making more self-pitying mix CDs until his bandmates convince him to help track down a top-secret rock concert. Meanwhile, Norah (Charlie Bartlett's Kat Dennings) and her hard-partying pal, Caroline (Ari Graynor), set off on the same journey. Nora had never met Nick, but she already had a crush on him (While attending the same school as Tris, she's been enjoying the mixes Nick keeps making--and Tris keeps throwing away). When the inebriated Caroline goes missing, they spend the rest of the night racing around the Lower East Side in his Yugo looking for the friend, the show, and trying to avoid Tris (Norah's ex-boyfriend, Tal (Tropic Thunder's Jay Baruchel), presents further complications). Peter Sollett's follow-up to Raising Victor Vargas aims to please several audiences at once. It starts out like a less dirty-minded Superbad, morphs into a post-millennial After Hours, and ends as a Big Apple take on Before Sunset. It's sweet and funny, but could use more of its own identity, though Cera and Dennings make for an appealing couple and the supporting performers, especially Graynor and Kevin Corrigan in a wordless cameo, enhance the proceedings considerably.
