Out of all the things to complain about this is what sends everyone over the edge? Lol
I had no problem with it. Did they explain why the White Ranger was a completely different suit compared to the Zyu Rangers suits? No.
What would be the point of explaining two teams of Rangers we never saw before? People would scream "Plotholes!!". It's stupid to even complain about something so small. We heard the Maskman suits were called "Blitz". That's good enough. God knows how everyone would react if they said the Dairangers weren't related to MMPR White. This was a good nod to the adult fans that always wondered if Saban or Disney would ever use the Dairangers, Flashman and Maskman footage. They give us a subtle nod and that's all.
Besides, the idiot behind this mess was FIRED for his creative incompetence along with most of his staff. What else can be done about it?
