Let's be realistic.

Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

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

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.
