Pirates and HM Both have stories -_-
Not sure if serious...
Anyway, Disney can't win. Disney gets derided for creating stories "Why does everything have to have a story?!", and now, it's decried for a ride without a story. DIYDDIYD.
Anyways, NRJ does have a story: You're sight-seeing on another planet (moon). You're observing a conservation operation making up for the mistakes humanity made. Total metaphor for what's happening on earth now. Totally the story of almost all of Animal Kingdom. And so the conservation company is letting you see the flora, fauna, and inhabitants of this moon up close.
It's pretty much the Safari ride but in a different environment, only there is no Little Red, at least, not any more. Some people miss the Little Red story, others don't. It's a matter of taste.
Can one wish that this particular ride had it's own self-contained episodic story? Sure. Does the lack of such a story make it a bad ride? Again, that's a matter of taste. If one thinks it's a bad ride for the lack of story, then I'm sure that one will boldly proclaim how much Kilimanjaro Safari Trek also sucks for the same reason.
