Saw the live adaptation on my Netflix recommendations, thought it was interesting, then I figured I should watch the original first. Was a couple episodes in when I decided to just browse through the episode list and see how many were there left.

The descriptions for the last two episodes give away the identity of the killer. I went and looked if the episode descriptions for the live adaptation also spoil the killer, but they don't. So only the episode descriptions for the anime spoil the identity of the killer.

Finished the show nonetheless. However, it definitely would have been nicer if I hadn't known who the killer was beforehand.
