Any episodes/seasons you had to skip and why?

I usually love watching the show and recently I have been rewatching all the seasons with my partner and we are currently on season 15, usually I am not very overwhelmed with the episodes/plots however the last episode of season 14 and any episode of season 15 involving suspect William Lewis was just TOO MUCH and I know stuff like this happens in real life and all, but I feel like they kept dragging out the episodes with him in it. And how it was so hard to get Olivia and all his other victims justice, and it was so taunting and infuriating omg I just had to skip them. What dod you guys think about the episodes involving him, and which ones did you guys have to pass if any?
