Very funny and very dark. Must be seen to really have an idea about it. Too bad that Paul Bartel did not do more movies.
Leonard Maltin/Plot synopsis:
Delicious black comedy about the Blands, a super-square couple who lure wealthy swingers to their apartment and kill them, which both reduces the number of ``perverts'' and helps finance their dream restaurant. Sags a little here and there, but overall a bright, original, and hilarious satire; Paragon has a super bit as a sexshop owner. Directors Joe Dante and John Landis also appear.
