What’s it all about? Three lively British lasses go on holiday to Majorca and pull a group of guys crewing a yacht.

They set sail and party hard – but when a terrible accident happens, tempers fray and things turn very nasty indeed.

What’s good? The build-up is the best part of this horror film – anyone who’s partied with their mates abroad will recognise the characters and scenarios.

It’s darkly funny in places, and also very sexy.

What’s bad? Once the action kicks in, the film becomes less believable and people make ridiculous decisions.

It’s also gruesome and horribly cynical about human nature – none of the characters are nice enough to root for.

OK! verdict: There’s fun to be had from this risqué horror, but by the end you will want to abandon ship
