Random Thoughts.....What Are You Thinking?

I still don't understand how Japanese anime/manga fans enjoy a series that has such insane amounts of stupid

There's this new anime adaption of a light novel or whatever called "shinmai maou no testament" and the chick wakes her new stepbrother up by sitting on him and then she starts grinding to make him get up and of course she falls off the bed and he gets up and falls down on top of her

Later she takes a bath and gets dizzy and *** collapses and he enters to see if she's okay and of course she's naked

Even later she forms a master-servant thing with him and it gets reversed so he's the master instead and if she shows disloyalty she gets 'cursed' by the magic (which was made with the magic of a succubus) and starts getting super horny and the only way to stop it is for him to fondle her ***

What the *** kind of retard would enjoy this ***? WHY would they adapt this instead of something that has a great story and would likely make them feel proud of their work after adapting it? I would never want my name associated with garbage like this; I'd rather be the person who adapts something great, even if it doesn't sell as much.

I really don't understand Japanese fans, how they can go nuts over this garbage instead of something with a really good story, characters with depth, and a world that is rich in detail. Not just a bunch of stupid fanservice.
