An excellent fun show with largely harmless action
Live action shows are, in themselves, not more adult or damaging than cartoons. I think something a lot of parents forget is cartoons these days are often quite energetic with the violence; but it's how that violence is played that counts. If kids can sit and laugh at Spongebob dropping a house on an innocent person (or rather fish person), biting their nose, and jumping into their eyes with spiked cleat shoes (no really) can elicit laughter and not turn kids into some kind of public menace; then seeing the Power Rangers protecting innocent people and attacking monsters is fine. The heroes and heroines are played by likable people, with good character arcs and nothing done in bad taste. Plus the effects and cinematography I find superior to a lot of movies so it's a nice treat to watch.
