No? Why should it aim for adults? It's a kids show designed to sell toys. I don't want a 2 parter about the Pink senshi contemplating suicide after having a miscarriage mid-battle, the Green senshi dealing with a heroin addiction that eventually takes his life, or the Red senshi finding out his fiancée, Yellow, is cheating on him with his best friend Blue. It's a kids show and we like watching kids shows for FUN. Just have FUN. It's why something like GochiUsa is popular, it's nice and happy and upbeat to help escape your troubles.

And Ex-Aid has an apparent dark tone? Even Gaim wasn't full Urobuchi this early on. What you're seeing is the villain build up. "Oh who are these guys? They're brooding in the dark and talking ominously, I'm intrigued." That's not really "dark" so much as it's "part and parcel for the series."
