This movie is one episode - one episode in a long saga of action and insanity that is the Power Rangers Universe. Quite honestly, many people just don't understand it, but it dosen't matter. Power Rangers is the most watched kids' show of ALL TIME, beating Pokemon, Thundercats, Voltron, Sesame Street, and whatever else you can think of, with a toy series that has sold in excess of 5.5 BILLION dollars worldwide, and is thus the #1 action figure of the DECADE, beating Pokemon, Marvel Comics, and Star Wars (all of which are superb franchises - Pokemon is hilarious, and Marvel and Star Wars are just legendary giants in the business). You don't honestly think that all of these fans are KIDS, DO YOU? Not possible. Just Not Possible.
Power Rangers is great. It's got everything. Don't take my word for it. Go. Suspend Disbelief. Dispel Preconcieved Notions. Don't be concerned with foam rubber and spandex - look at the storyline. See the show. Watch the movies. Judge for Yourself. And May The Power Protect You All.
