Since we're approaching that time of year when critics start making those "best-of" lists, I think it's safe to say that most of what released in 2009 easily proves the adage that dates all the way back to Ecclesiastes 1:9—ultimately, that there's "nothing new under the sun."

While recycling old ideas was basically status quo, surprisingly enough, borrowing from other otherworldly space-age flicks including Stars Wars, Close Encounters of the Third Kind, E.T. and Alien actually elevates Planet 51's overall enjoyment factor. 

Considering that the scriptwriters never really made the most of the somewhat original concept they started with, namely having aliens being deathly afraid of the humans (rather than the other way around), the sly references to far superior sci-fi fare prevent Planet 51 from being a total dud. In fact, it's sort of fun waiting to see what they'll spoof next.

But in a year where there's been so many alien adventures vying for our attention (see monsters vs. aliens, race to witch mountain, aliens in the attic 9 and more), there still needed to be something more compelling to really set Planet 51 apart.

With subpar storytelling and lackluster animation, not to mention a clear lack of enthusiasm from its celebrity vocal talent that includes Dwayne "The Rock" Johnson, Jessica Biel and Gary Oldman, there's simply not enough here to make it a must-see.

Set in a decidedly 1950s-esque world populated with little green people with four-fingered hands, webbed feet and no noses, those living on Planet 51 often believe whatever they see at the local cineplex, namely that humans are always looking for a few good alien minds to control.

Then adding fuel to the fire, an actual living, breathing human shows up in his auto-piloted spaceship, a dim-witted, narcissistic astronaut named Chuck (voiced by Johnson, although I never would've known because he sounds so different). Even though he has no intention of harming anyone and comes across as nothing but friendly, what the green people see is nothing but one ugly creature intent on hurting their peaceful planet. So they start fleeing—immediately.

But once Lem (Justin Long), a science geek who just scored his first professional gig, actually starts spending time with Chuck, he quickly realizes that his people are wrong and hopes to convince them of Chuck's good qualities.

Unfortunately, everyone is too busy trying to escape from Chuck to hear, let alone give much thought to Lem's findings, which eventually gets him into one sticky situation after the next. But even in the movie's more dramatic moments, there's a whimsical, madcap spirit that prevents things from ever growing too dark or serious.

Sprinkled in with all the silliness, the kind that would be quasi-entertaining to anyone younger than, say, 10, there are few valuable insights, too. Revolving around familiar, well-covered territory like friendship, not judging people too quickly (or harshly) and the importance of figuring out why we believe something, rather than simply accepting a truth we really haven't researched ourselves, Planet 51 is definitely deeper than some kiddie fare goes, but isn't exactly revelatory.
