“Who Invited Them?” (* out of four) was a disastrously lame suspense potboiler about a couple (Ryan Hansen and Melissa Tang) who have a housewarming party but one couple (Timothy Granaderos and Perry Mattfeld) stubbornly remains after all the others leave and they begin to suspect that they are nefarious strangers out to take over their minds (and souls). Or something like that. Stilted and stupid and goes nowhere slowly. Don’t bother “inviting” yourself to this ridiculous clunker.
