Tonight not one but two new Us sitcoms step forward in an effort to fill the Friends-shaped void that's been left in E4's schedules. Happy Endings and Perfect Couples are a product of the Us networks' recent fascination with romcoms. Look beyond the subtle differences – one sports an uncomfortably suggestive title, while the other has already been cancelled – and there's not too much to separate two cookie-cutter comedies. In fact Happy Endings and Perfect Couples are so similar you could probably switch the characters, jokes and storylines of both shows without noticing much of a difference.
So what are the must-see sights on a tour of tellyland's finest romcoms? Join us as we separate the Hugh Grants from the Hugh Hefners in our run down of the six best.
