good back-story, and good acting

It's not great by any means, but it's a pretty good movie that didn't leave me filled with regret for investing time in it.

If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

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.
