TV gagster Seth MacFarlane follows up his Ted with this joyless vanity (and I do mean vanity) project – a bloated spoof western in which he plays a pottymouthed sheep farmer who falls for the wife (Theron) of a feared gunfighter (Neeson).

The thing drags its heels like a rattler-bitten bison, and while some of the wisecracks might conceivably have looked good on paper, they're not helped by MacFarlane's delivery: like a dead gunfighter, he needs to work on his timing. Sarah Silverman, though, brings some cheerful obscenity as a raunchy yet coy saloon belle.

It's essentially Blazing Saddles, only the fart jokes aren't quite as fresh.
