'What's Your Number?' starts badly and goes downhill from there

Based on the novel '20 Times A Lady' by Karyn Bosnak, 'What’s Your Number?' centres on a 20-something career girl who imposes a strict limit on the number of men she is allowed to sleep with before she finds her Prince Charming.

When she hits that limit – 20 lovers – the only choice for the beleaguered heroine is to revisit her old flames, hoping that she missed a diamond in the rough the first time around.
