I didn't liked it too.Started interesting and was enjoyable, but after that get way into psycho territory and the enjoyable factor went into the trashcan.That is of course because I hate yanderes.
So my opinion- in short if you like yanderes this is probably the best anime for you.If not, you won't like it much and better watch something that you'll enjoy more.
For the yandere fans- probably 99,9% of them know it but still good to remind:

It's realy hard to stop listening those videos lol
