Oh dear. It seems not even Ben Stiller's trademark everyday Joe routine meshed with Vincent Vaughn's quick fire patter Schtick can save this domestic sci-fi comedy from going nowhere fast.
As for Jonah Hill, he really should know better having made far superior offerings such as Moneyball and 21 Jump Street.
The plot, if you can call it that, involves a DIY manager (Stiller) starting a neighbourhood watch after one of his employees is slaughtered. Roping in the services of Hill, Vaughn and Richard Ayoyade (the movie's only plus point), they attempt to find out who or what was responsible.
The gags are thin, the improv, especially from Vaughn and Hill downright embarrassing, and the tone is just wrong. R/18 rated humour is great when it works, but this just doesn't.
Hill threatening to kill everyone at a party except a couple of twins he was chatting up is far less funny than suggesting a witty ultimatum if they don't do what he wants, but it seems they couldn't be bothered with a pithy retort.
Oh and by the time we do see an alien it's a dire letdown. Bad animatronics and make up make this look like an indie flick rather than an A-list comedy.
Sadly there's also a subplot about Stiller's character firing blanks.
Apt for a film that is one huge misfire from the first frame to the last.
There are a couple of laughs here and there, but The Unwatchable may have been a better title.
