Probably also this setting's approach to sex.

Impressions:

You could remove every bit of the corny/dumb "sex-powered" premise, and nothing in the episode would change. I mean that quite literally, as it doesn't actually engage with that premise at all. Not on the level where it yells out an explanation and then someone faceplants to show that it's meant to be taken as a joke. Not that they explain it at length. Not really anything at all. The closest it comes is that the main girl is a bit of a standoffish bitch because she's repressed, but then they hold hands while running away from a bug, which makes her remember a time when she wasn't a standoffish bitch, so she grows into a standoffish bitch. 

I guess at least the male lead is already in the hero role and fighting monsters, so we're spared any part of his origin story where he's a pathetic loser who just wants a regular life, but then we have to get to the 'fights' being someone grunting, their clothes explode, and then they punch a bug. That's it. That's both the fights. The entirety of both the fights. Not even well animated clothing exploding or a punch. It's not even taking its premise and trying to run with it to ridiculous levels. It's just a really generic, really poorly made power rangers knockoff show that they've shoe-horned about 15 seconds of fanservice into to try to give it a gimmick.
