Oh I forgot. Thanks for reminding.
Problem is I have not seen one of the 2 Wicker Man films, so I can't judge. A friend responded also with the older one to the same question.
But I said before that there are sure some (many?) horror films with a bad ending. Cronenberg's Shivers for example.
The question is if these are comparable with a good/bad situation in (all sorts of) adventure films.
I will try to see the 70s Wicker Man, but have no clue how to get it.
