True, they won't really notice unless you were really looking and know what to look for.
I still hope they at least explain why everything has a pirate motif. At least with Megaforce it's easy not to explain the Angel theme since almost nothing could be seen that way. The Zords are animals (common in Power Rangers), the suits are generic enough to be anything, the cards could be applied anywhere, easy to get away with.
But Super Megaforce is blatantly pirates. Their swords are cutlasses, their guns are flintlock pistols, the red Zord is a pirate ship, they control their Zords with wheels found on ships, the Megazord has a giant cannon in his chest, and their emblem is two swords crossing. People will notice this.
