Disappointment for a huge fan!

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.

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.
