Whether intentional or not, I believe Mighty Morphin' Power Rangers turning up now was perfect timing on behalf of Saban/Toei. I'm sure you've noticed fatigue regarding action media being cynical, self-depreciating or depressing. Power Rangers on the other hand was always earnest, even in its "darker" seasons like In Space. It might have been a wild American take on Super Sentai, but it did keep some of the cheesy charm when the format was translated, and people seem to want to return to when heroes were heroes, instead of depressed washouts who seem to be aware of, and hate, that they're in a superhero property.
