I don’t mean stuff that was obviously bad on sight (to you) and so you didn’t bother with, or even necessarily content you just checked out of before the first episode was done. But a series that you ultimately felt wasted your time and abandoned due to its total lack of quality.
You know the show is gonna be bad when not even the trailers look horrible. I distinctly remember cringing at some of John Bradley’s lines in the first couple of teasers. I think they must have realized that his dialogue was awful because they started cutting his character completely out of the later trailers.
