They’re universes where the Boy Scout virtues work. They follow the rules of Boys Adventure, not Gritty Realism. Dog Days mixes it with a healthy dose of cheesecake, but the key word is healthy; there’s shock and embarrassment when a special attack manages to destroy a female character’s clothing without harming her in any way, but there’s no fear, no leering, no dominance, nothing negative. It’s all good clean fun.
I think the closest Hollywood has come to this (the feel, not the special attacks; pity) was the 1996 version of The Phantom, featuring terrific performances by Billy Zane, Kristy Swanson, Catherine Zeta-Jones, and Patrick McGoohan. It tanked, of course; too wholesome for the market.
