It's sad that the last season had to be its worst after how literally flawless the fourth and third one were. It was still great, but yeah.
It's always bitter for a fan if a the last season is the worst. If it's in the middle you can kinda erase it from your memory but if the last season doesn't fit it kind of puts a bummer over the entire show
Very recent examples for me is True Blood. Seaosn 7 was possbily the worst season I have ever seen on any show in my life
