Did you ever dropped a series after multiple books? Not sure if I should continue Witcher after book 5 (no spoilers)

Hi,

Witcher is the first really long series I’ve read. I am at the end of book 5, and I force myself to finish the last 50 pages. I completely lost interest of 2 of the 3 main storylines, I don’t like writing, as it feels too slow and repetitive, and heroic. I feel like the characters have been changed and modified as well to become very predictable and narrow minded.

My point is, I am not enjoying it, I struggle to finish this one, which I probably will just to give good stopping point.

Did you ever dropped a series after being so deep inside?
