i saw a few people say this about a film i watched. it seems like a bit of a silly thing to say imho. have you ever felt this way about a film? (we'll extend it to last few minutes or whatever). show your workings. there's definitely films i've seen where i've thought *well that was a stupid ending* but it's still a good film if you've been enjoying it up til that point. if the ending is really silly (ie, it was all a dream, she was commiting the murders all along despite it not being physically possible) i tend to just ignore it
