Review of School Days

Now, I'm not here to write a professional review or whatever. I'm here to explain the simple details this anime is showing you. But first, I have one question: What the fuck is wrong with the guy who wrote this? In this anime, EVERYONE is an asshole, EVERYONE. Except for a guy called Sanagawa Taisuke. I finished this anime, and it was so frusturating, I really barely finished it. The story starts off with a really nice atmosphere, nice animation. But soon enough the story gets so fucked up, I almost threw my monitor out the window. Basically, what the anime is: Betrayal. Too much of betrayal. Butit's not only that, a bunch of people bullying, I guess, one single girl in this anime. Everyone is an asshole in this anime, even the main character, actually he is the biggest asshole in this whole series.
But I did, kinda, like the ending, it was so fucked up, that I was literally sitting and thinking: "What the fuck is wrong with the guy who wrote it?".
Every episode I was mad at every character, like, plain mad, angry.
I'll give it a 6, if not for the ending, I'd give it a 4-5.
People, if you're into Romance and stuff, don't fall into this trap, you'll be very mad at this, this is just the biggest WTF anime I've ever seen.
