What anime do you think had good writing but was not enjoyable?

Similar to the last thread.
Do you have such anime? Nothing comes to my mind at the moment but I am sure there are some anime like that for me.

For me, Erased. I liked the idea behind it but i just didn't enjoy it

Good writing but not enjoyable?
