“Mighty Morphin Power Rangers: Once And Always” (**1/2 out of four) was a zippy continuation of the blockbuster series about the Power Rangers (Billy Cranston, Steve Cardenas, Walter Jones, and others) who are confronted with a global crisis and are called on to save the world once again but soon find that this might be a far more dangerous mission than they realized. High-energy movie with lots of action and visual effects but still mostly for fans and young viewers. Come to think of it, though, this is better than the 2017 feature-film adaptation and is probably on par with the previous 1995 version.
