The parents in this film take a definite backseat to the kids in the foreground, led by talented relative unknown Carter Jenkins. In fact, all the young actors are pleasant enough to watch (even Tisdale is tolerable), with Robert Hoffman as the clear standout. The young up and comer takes on the traditional bad guy role of “douchebag polo-shirted, yellow-convertible-driving boyfriend”, with a twist once the aliens highjack his body. The guy shows no self-consciousness here and takes absolutely no shame in goofin’ it up for the camera, which results in easily the best laughs in the film.
As for the aliens themselves, well, it’s been done better. They’re all entirely digital, and the FX work isn’t terrible, but certainly not groundbreaking. Since they’re all pint-sized, they aren’t very menacing, but they're here for comic relief just as much as they are for thrills, so that’s to be expected (unfortunately they’re not that funny though).
The ever-evolving dynamic between the siblings, along with an E.T.-esque relationship between a friendly alien and a little girl give the film a humanity that seems to be sorely lacking in the majority of what passes for family comedies these days- mean-spirited affairs where fat jokes and fart gags [and Eddie Murphy] take center stage.
The action, despite taking place entirely inside a house (and in the backyard) is pretty cleverly crafted and well-done. A slinky is used to restrain an alien, a fire extinguisher as a jet propulsion pack, that sorta stuff, and it works. Oh, and we also get a sweet kung-fu grandma fight scene courtesy of Doris Roberts (Everybody Loves Raymond and Grandma’s Boy). Sweet.
Alternate Ending (2:48) - Fairly entertaining as it's pretty different than the original. However, the FX aren’t completed so the aliens look worse than claymation.
Gag Reel (4:54) - This gag reel is…well…cute. Yeah, that’s the best way to explain it. I’ll be honest I did laugh more than a few times.
Behind the Zirkonians (15:26) - A barely-animated comic about the Zirkonians that provides a glimpse of life on their planet. Not my cup of tea.
Meet the Zirkonians - An in-depth, interactive profile of each of the four aliens, where you can click on different parts of their bodies to learn more info about each of them. Pretty cool stuff.
The Ashley Encounters (4:09) - As if this DVD didn’t already jock Tisdale enough, they give her her own special feature where everyone heaps praise on her. Kind of an insult to Kevin Nealon and the other more accomplished adult actors if you ask me, but I guess they aren't this film's target demographic.
Lights, Camera, Aliens (9:31) - This is your standard behind-the-scenes featurette. If there’s anything worth seeing here, it’s granny’s stunt double. CREEPY and AWESOME.
Kung Fu Grandma (1:21) - A fake commercial to purchase your very own grandma-controller. Definitely skippable.
Brian Anthony “Electric” Music Video (1:36) - A montage of the alien scenes in the film, with a cheesy pseudo rap/techno song over it....why?
"Life After Film School" with Producer Barry Josephson (27:31) - A Fox Movie Channel show where three film students sit down and interview someone in the industry. In this case, they interview the film’s producer.
The Blu-ray also includes a separate Digital Copy to play in your minivan for the kiddies on the way to your next family vacation.
