That sure is a movie

Not a fan?

The ending very specifically felt like he realized he was running out of film and had to write an end real fast

It was like the opposite of a climax

Some of the concepts were fun, the mental break scenes had some really neat cinematography for that era.

But I think in review it was mostly just a movie about a guy being a real uncomfortable creep

Which, given the movie on after was Rear Window, feels like a theme

It wasn't bad, per se, but I'd give it like a 5-6/10
