Avis Metacritic

Like a good episode of "Smallville": You may feel a bit silly watching it if you're past high-school age, but you just might have a good time.

Brit hunk Alex Pettyfer has grown into a solid and quite interesting lead to build this potential sci-fi movie series around.

While Caruso will fail to win over adult reviewers, I Am Number Four will connect with teen moviegoers anxious for a new young adult fantasy fix to hold them until the next "Twilight Saga" hits in November.

The movie is a mixed bag, with many of the elements fun and intriguing, but since this is also a Michael Bay-produced movie, CG monsters and cartoon bad guys gum up a third act.

A flashy, lunkheaded sci-fi extravaganza sure to appeal to teenagers who like their interplanetary warfare bloodless, their high-school soaps squeaky-clean and their numbers countable on one hand.

Nothing but a million little pieces from prior superhero series and the "Twilight" saga.

Producers Michael Bay and Steven Spielberg deploy an arsenal of noisy special effects to demonstrate the invaders' high-tech superiority, which makes Olyphant's inability to breach an Internet firewall look pretty silly.

I found the mythology of I Am Number Four vague and sloppy.

What we have here is a witless attempt to merge the "Twilight" formula with the Michael Bay formula.

Check the credits: That move is ripped straight from producer Michael Bay's playbook.
