The Power Rangers was already live action, so it has that going for it. Animated series especially seem to have trouble translating to live action big screen deals. I've heard the first Power Rangers movie had a ton of people in it that turned out to become pretty big names in the industry. (As in production staff, not actors.)

Especially the second Transformers movie was just smurfing confusing. It was just a cluster smurf of rapidly moving camera angles, and tangles of robots rolling around in a combat ball.

I'll take Orson Wells as Unicron and the original animated movie every day of the week.
