It's entirely possible that sending the audience out feeling lousy was intentional

A movie that not only functions as a solid scarefest but a razor-sharp satire.

The movie runs out of plot and jokes well before the end of a two-hour running time, long for a light comedy.

It’s fine. It's literally the definition of a fine movie. You’ve seen it before, you know every beat and outcome before the characters even do. Only question is how much escapism you’re looking for.
