So you basically judge the game and story before you even properly have started it? Eh, suit yourself, though that's not exactly fair, and since you didn't bother going further than that, you judged prematurely.
First off, you can choose who to date and who not, and there is actually quite a lot of H-scenes there, some more than others but it does go all the way with each of the characters. Also, your actions may also effect your relationship with someone else, mostly in a negative way.
Oh and by the way, calling something completely shit and waste of time before you have even REALLY tried it out yourself is pretty damn ignorant. And even if you don't like the game, for whatever reason, there are more polite and better ways to express your opinions, such as "I didn't like this and that, so it's not for me", that's better than outright calling it shit, that doesn't exactly motivate the devs to try and make things more to YOUR liking, nor should they for that matter.
