The direction is all the same, isn't it... This review expresses strong dissatisfaction with the "capture and immediate sex" development in adult works. Indeed, the pattern of capturing the heroine, chaining her up, and jumping straight into a sex scene as if to say "Now, let me partake" is quite common. But the author seems to be saying that as a flow unique to AV, there should be a bit more ingenuity.
For example, if you start from the moment of capture, you want some unpredictability in the subsequent development. Like a surprise hit or push bunt when you expect a sacrifice bunt, it should give the viewer a sense of excitement, wondering "Now, what's going to happen?" Capturing her, laughing "heh heh heh," starting sex, and the heroine just resisting with "no way"—I can't understand what's interesting about that.
As a more specific scenario, imagine a scene where a monster captures the heroine, chains her up, and even tortures her. Then an enemy scientist joins in, approaches intending to torture her, but is captivated by her cuteness and, without the monster or comrades noticing, suddenly starts groping her pervertedly... I want a development that makes the viewer think, "No, no, you can't just take it to sex. What the hell are you doing, this guy!"
Currently, it's just a cycle of "captured → does lewd things → gets defeated," and the development of naturally going into sex is really not interesting. This is nothing more than an AV just messing around with a cosplay girl. The enemy's original purpose should be to defeat the heroine, but they immediately go for sex, which is why it's boring.
For example, if a subordinate is about to do something lewd, a higher-up could stop them, saying "Don't waste your energy on trivial matters," and then when the subordinate isn't looking, the higher-up attacks the heroine with full perverted intent... That kind of reverse thinking could work. Also, having her almost fully clothed is not interesting either. What should be embarrassing after it's over is being fully naked, but if you strip her completely like this heroine, she just looks like an ordinary woman. That's why a delicate balance is needed, like leaving only the black parts of her upper body while making her fully naked.
In the end, the enemy's purpose is completely unclear. To be blunt, isn't it just that they want to have sex with a woman? Instead of such monotonous developments, I think what's needed is a story with unpredictability and tension that stimulates the viewer's imagination more.
