It appears there’s a Hollywood prerequisite for all romantic comedies to revolve around weddings or actors over the age of 30. But there is a music-obsessed, MySpace generation of movie-goers who want young romantic comedy characters that they can relate to.

For their consumption, Hollywood has delivered “Nick And Norah’s Infinite Playlist,” a young take on the genre that is enjoyable, despite its predictability and conventional nature.

Based on the novel by Rachel Cohn and David Levithan, the film introduces us to the male title character Nick (Michael Cera). The high school student/alt-rock bassist is heartbroken, sending mix CDs to express his undying love for his ex, Tris (Alexis Dziena). She thinks it’s pathetic, but her classmate Norah (Kat Dennings) loves the music and wishes she knew the identity of the mystery mixer.

Norah, herself unlucky in love, goes clubbing with her best friend/drunken liability Caroline (Ari Graynor). Here, she meets Nick playing a show and asks him to pretend they are a couple to look good in front of Tris. When Tris catches them together, despite already showing up with a new dude, she is obsessed with luring Nick back and sabotaging Norah’s chances.

But Nick and Norah don’t initially hit it off after their awkward introduction. The two argue while club-hopping in Manhattan in Nick’s clunky, yellow Yugo while tracking down a secret gig by the band Where’s Fluffy. While trying to find the band and recover Norah’s drunken friend, they bond over music and broken hearts when Nick learns Norah’s troubles with her ex Tal (Jay Baruchel), who later rears his ugly head.

The previews alone give you an idea how the story may turn out. And you wouldn’t be too far off. You may also get the sense from the film’s hipster marketing and having Michael Cera star opposite a sassy, young female lead that the film is “Juno.”-esque. There, you would be mistaken.

Where much of “Juno” seemed to buck convention, “Nick and Norah” is happy to stick to it. The film is shot and well-edited, with plenty of NYC skyline, cool cuts and a killer soundtrack, but with the exception of one twist about Norah’s V.I.P. identity, you can see everything else coming.

Luckily, the convention doesn’t kill the comedy, thanks to charming performances, sharp dialogue and several funny scenes. Cera leads the cast with the film’s funniest and most pitiful portrayal. Despite using the understated, quiet-guy technique seen in hits like “Superbad” and “Juno,” it still works wonders. Dennings (“The 40-Year-Old Virgin”) also does a good job complementing Cera with genuine chemistry and some snappy delivery of her own. Some very funny scenes also keep the film from stalling out, like when Nick’s yellow Yugo is mistaken for a cab or their encounters with homeless crazies and transgendered Christmas performers. But other scenes are more cringe-worthy, like Caroline’s dilemma involving her gum, a cell phone and a bus station bathroom stall.

It may be a typical romantic comedy dressed up in hipster clothes and indie rock for a younger crowd, but “Nick and Norah’s Infinite Playlist” is still 90 minutes of easily digestible and satisfying entertainment, no iPod or MySpace page required.
