The film has a somewhat decent premise, (where 9 alien kids from another planets, along with an assigned protector, are hiding out on earth on various continents far apart from one another. One by one, the children are being hunted down by another race from their planet to exterminate them, and their bloodline, which passes down powers, or legacies, from parent to child), though just bits of the alien kids backstory is hinted at here and there. The first 2 acts provide some introduction to Number 4, as the first 3 have been terminated, so #4 and his protector go on the run, and end up in Ohio. The opening and middle acts are pretty much by-the-book, and uninspired teenage high school drama, but the final act delivers quite a lot of action and use of powers in a showdown between him, his new friends, and the bad guys. As a set-up for a franchise of such films, I just don't know if we'll see another follow-up due to box office performance. Time will tell. I give it 2.5 stars, or a grade of C+.
