The very definition of mediocre. Basically just a group of talented comic actors trying to prop up a barely there premise.
While aliens play a significant role, the film has little to no interest in them and doesn't even attempt to create a 90-minute plot around them. There's tons of lengthy filler - Stiller can't have kids, Vaughn has a creepy obsession with his teen daughter's burgeoning sexuality (the film's depiction of female sexuality is off-putting to say the least) - and lots of (seemingly improv'd) banter taking up the runtime before a lame action climax.
This film really is a study in how star-power can (almost) save a movie. The leads all fall back on their usual acts: Vaughn's boorish motormouth riffing, Stiller's comedic anal-retentive awkwardness, Hill's a crudely hilarious borderline-psychopath (his loner fuck-up character keeps an arsenal of guns in his room. Apparently Fox was less worried about real-world parallels than Warner Bros.) and Adoade, well him I'm unfamiliar with. But he's pretty funny too. There's also solid support from Billy Crudup, R. Lee Ermey and Will Forte.
Yet they're all in the service of such shitty, paper-thin material. There's no outlandish spark or memorably weird moments. The no doubt B.O.-killing R-rating feels under-exploited. The laughs are ultra inconsistent.
It's a forgettable, inoffensive timewaster, nothing more.
