This is a good one, for these reasons:
1. Interesting story about "typical" people caught up in frightening and, ultimately, dangerous situation. No..not gangsters, spies, etc. Just..."extended family."
2. Good performances from all major players, especially Leslie Manville (Princess Margaret, The Crown) as the control-freak "in-law."
3. More than a good "plot," a great theme: life is...loss. Now, what are you gonna deal with it?
And good because of what it isn't: a comic book "super hero" movie.
In 2022-21, that's very good, indeed.
