A Morpher with all the sixth rangers (Robo Knight included) on it as well as a key specifically the same as the other Rangers is found inside a rock on another planet with absolutely no explanation and thinking that big Question Mark needs to be explained even in the slightest is nitpicky? I disagree. And yes, it does become bad because it wasn't a real explanation. It wasn't an explanation at all. You being satisfied with it doesn't stop it from being awful. It wasn't done well there.

"Because Gosei" doesn't even work for this specific thing is because pretty much the first thing Gosei said was that he was "of Earth" so an inferred explanation that he made them and put them in a rock on another planet doesn't make a lick of sense. Eitherway the fact that the show has been utterly crap at explaining anything when it comes to these powers doesn't stop this part from being utterly crap too.

I guess the Q-Rex thing is vaguely an explanation but it isn't even close to satisfactory. The Q-Rex wasn't even in the Year 3000 and the fact that MMPR Green and DT White are used without anybody even pointing them out just adds to the confusion.

But no, the scene with the MMPR Green, Quantum and DT White keys glowing was the first time the sixth keys were there, similar to the Megaforce keys suddenly spawning on the wall in Episode 3. Everyone was expecting something with Silver to happen to explain their appearance, especially considering they avoided using them last episode, but alas, Super Megaforce. I'm beginning to think the Keys will never be explained.

I don't think legitimate holes count as nitpicking, really. I accept real nitpicks like "why did he say it took him so long to fix a ship" and "why did he take it down with a slingshot" because they are really nitpicky but no explanation of a Power(s) or a returning Zord are significantly bigger issues and I really don't think calling them nitpicks are fair. Sure, they're ultimately ignorable, but you could say that about most problems of any show, just because you can enjoy a show flaws and all doesn't stop the flaws from being flaws.
