Imagine the cast of Beverly Hills 90210 being dropped into Xavier's School for Gifted Youngsters from the X-Men movies and you'll have a sense of the uneven pastiche that is I Am Number Four.
The film starts out with an exciting action scene where we see creepy aliens chase and kill Number Two in a lush jungle. After being outed as "some kind of freak", we cut to teen John Smith (Alex Pettyfer) and his guardian Henri (Timothy Olyphant) throwing their belongings into their car and burning photographs and anything else that connects them to the Florida community. "This is the part I hate the most. The running." John explains in a lengthy voiceover, as they head to the tiny town of Paradise, Ohio where they just happen to have a long-vacant house on the edge of town.
Then the backstory really gets confusing. John is one of nine alien kids from planet Lorien who have special "legacies" that make them extraordinarily powerful. Henri is a warrior assigned to guard John. The bad guys are also aliens, the Mogadorians, or "The Mogs", and after invading Lorien they're tracking down The Nine to kill them, apparently in preparation for invading Earth. How those two tie together? I've no clue.
The real problem with I Am Number Four, however, is pacing. After an exciting first ten minutes, the film settles into a cliche-laiden teen school soap opera, including John, the lone outsider, the bullied science nerd Sam (Callan McAuliffe), the jock bully Mark (Jake Abel) and his posse, and super cute Sarah (Dianna Agron), who falls for John which -- surprise! -- angers ex-bf Mark. Yadda yadda, you've seen all these trite interchanges a thousand times before on the big screen. After an hour or so of High School Drama, the Mogs finally show up, along with the sexy Number Six (Teresa Palmer), and the action finally resumes.
I Am Number Four wasn't a bad film, and it's certainly entertaining, but the pacing was awful. If you're a teen who digs action films, this might be a wonderful movie for you -- and the cast are all pleasant to watch, men and women alike -- but if you're used to more sophisticated action fare where the backstory is skillfully woven into ongoing action and adventure, you'll be yearning for something better.
