MR was of above average intelligence - it had more ideas than most contemporary SF films. That’s what people said about Vertigo when it was released. It has as much in common with Antonioni and Resnais as it does with other Hitchcock films.
MR was a fun ride until that horrible ending. The whole idea of the ex-wife just waltzing in and solving everything was just bad. If credits roll when Cruise is lowered into the cryovat it’s one of Spielberg’s best, but he can’t do unhappy endings.
They were right about Vertigo the first time. It’s dull.
