When a writer makes a super cool book series just to murder every character you loved in the end because they ran out of ideas and got lazy.
I spent 10 years with Harry and Hermione, and then they died in a stupid fire. What even was the point?
The last book was just a bunch of people dying for no reason. Why? Just why?
I cried when my favorite character got killed off. It was like the author had a grudge against me.
