Zendaya is good on Euphoria, but the win was definitely laughable when you consider she had Linney, Oh & Comer in the same category. There was probably better acting by Oh just in the 2 seconds when she found her husband stabbed in the throat than anything in Euphoria (yes I've seen the show) and that's before even getting to the fact that Euphoria as a whole isn't that good of a show compared to Killing Eve or Ozark. It's basically a mature version, slightly better written version of those nonsense CW tween dramas.
Anyways like someone said, the show has a hardcore fanbase, so it racked up votes while Killing Eve and Ozark split votes.
