Well, excellent, that's proved that! I thought The Princess Bride is the no 1 "no-one but no-one doesn't like it" film, yet CovertFoofle knows people who don't like it.
89% of critics thought Harry Potter 4 was good (rottentomatoes.com) but they are all staggeringly deluded IMHO. It was, from a storytelling perspective, shoddy. Borderline inept. So for me critical consensus is no guide.
(While I think of it, BTTF - though some elements are dated, again it's the genius core story and sublime storytelling that make this as loved as it is)
So we've proved that there is no such thing as a good film!
