Simon Pegg and Nick Frost's slacker-bromance shtick is becoming a tad sluggish, and it feels like an age since their exquisite Shaun of the Dead, and the excellent Spaced.
Here, the comic duo play sci-fi geeks who realise their dream of making a pilgrimage across America's UFO heartland, starting at a convention in San Diego before heading for Area 51. First they encounter redneck homophobes in a Midwestern café (how many times do we need to see this scenario?) before bumping into a foul-mouthed alien, Paul (voiced by Seth Rogen). Soon the feds (led by Jason Bateman) are on their tail. A pretty poor caper until, bizarrely, its rather lovely last 10 minutes.
