You know, I hate Power Rangers because I don't support adaptions, not unless we can have the privilege of seeing both the new material and the original, uncut material. But all this speculation does bring up something interesting...
Though they probably WON'T do it this way, I would TOTALLY see and support a new Power Rangers movie that was NOT based on a pre-existing Sentai. Everything completely new and original. The zords, the suits, everything. If they manage to do that, then I would care less if the quality was anything from as low budget as the actual TV show to as high as Transformers. And I mean that, considering how I loved the first Power Rangers movie as a kid. Not just because it was Power Rangers, but I loved how they handled the effects and the realistic feel the movie had.
To be honest, if they did the same for the TV series, make it all original instead of making it an adaption, I would support that too...
