The trailer for Banksy's Dismaland theme park is very, very dark

Banksy's pop up bemusement park 'Dismaland' opened in Weston-super-Mare last week, and first reports say it really is a viable alternative to the "sugar-coated tedium of the average family day out".

The dystopian paradise now has an equally dismal promotional video, in which a family decide to escape from mindless escapism by paying the park a visit.

The park's attractions, which include the chance to "navigate the high seas" full of refugees on a Mediterranean boating lake and a Jimmy Savile themed Punch and Judy show, definitely aren't suitable for all the family - and neither is the trailer, which has a nasty surprise at the end.
