“Black Widow” (*** out of four) was a sleek adaptation of the Marvel Comics story showing her origins and how she started off as Natasha Romanoff (Scarlett Johannson) and grew up with a sister figure (Florence Pugh) and a Russian super-soldier (David Harbour) who helped mold her into a highly trained KGB assassin and lethal fighting machine who would go onto save the world. Not a great film, as story is thin yet goes in too many different directions with different characters, but overall entertaining for Marvel and comic-book fans. Final half-hour action blowout definitely makes up for a lot. Johannson is strong as iron in the lead.
