TV Shows That Went Downhill After Season 1

3. '13 Reasons Why' (2017-'20)
Set in the aftermath of young Hannah Baker's (Katherine Langford) suicide, the first season of 13 Reasons Why flashes back in an attempt to discover why she did it. A number of her friends and classmates receive mysterious boxes of audio tapes containing Hannah's voice from beyond the grave. The format is ambitious and everyone seems uncomfortable the entire time. And if you think Season 1 is bad, you should see the follow-up seasons.
