Let's be honest. The Neo-Saban Power Rangers shows are horrible in almost every imaginable way. Profound laziness. Insipid lack of inspiration. Golden opportunities thrown out, shat on and flushed down the bog.
To so far willingly keep in Dairanger, Maskman and Flashman while not bothering with footage of Goranger and Jetman is bewildering. To meticulously re-film and edit out Goseiger costumes and replacing them with another ONLY to disregard that and throw in the regular Megaforce powers as readily available keys is confounding.
But why should I be surprised? It's just another testament to the emotionless laziness from the execs, who are too busy counting dollars to care about an established universe that has a fanbase beyond the most superficial of levels, depending very slightly perhaps on who the guy in charge of the script is.
They already killed it long ago.
