Good start, but then it gets ruined

good back-story, and good acting

The movie's not perfect, but it sticks the landing of its message. It was engaging - thrilling at times - and I personally thought it was a great time.

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.
