Gervais now seems adrift in some kind of sub, sub, sub Richard Curtis land, where character, mood and plot are simply thrown out the window and to hell with it.

Not funny enough to be a great comedy or impactful enough to be an emotive drama, this inoffensive, lightly amusing story drifts along without much sense of purpose.

Disappointing tale of '70s youngsters devoid of wit or insight.

This is a warm, even feel-good film that captures the tradition of its type with near-perfect clarity.
