Bizarre visuals, outdated humour and a needlessly abstract moral prevent this prehistoric offering from DreamWorks Animation from living up to its potential. The animation flows smoothly enough and the 3D doesn’t offend, but when it’s difficult to recognise the message, let alone the wildlife, it’s fair to say that something has missed the mark.

Everyone loves a buddy comedy, right? Sure the laughs are cheap, but generally they’re thick, fast and cheerful, with a plot that careers like an enthusiastic labrador to a satisfyingly predictable conclusion. Bless them, we say. Bless all who ride in them. Unless, of course, you’re talking about Hot Tub Time Machine; the laziest, dully-degrading, least funny bromance movie we’ve seen in some time, made all the more offensive by the evident comic potential of the cast. Oh dear oh dear. And the title was so awesome.
