Seen it before? No.
The movie The Truth About Cats and Dogs with Uma Thurman and Janeane Garofalo had a line about loving your pets...
Abby: We can love our pets, we just can't LOVE our pets.This movie reminded me of that because the admiration of the female Charlie, the niece to the real Charlie, for her uncle was really creepy. And there was also something creepy about the real Charlie...I'm sure it was a story telling device but he was duplicitous to say the least and I'm pretty certain he didn't really have a heart. It's thrilling but not nearly as much as the rest of Hitchcock's works.
See it again? Yes, surely I missed something...but I doubt it.
Own it? Why not?
Spoiler alert - glad Charlie snapped out of it in the end ha ha ha
