Season 1 was near perfect. Season 2 was a step down, but still decent. S3 was a massive disappointment. I find myself not caring about the continuation of this series any longer.
Wayyy too many tropes and ripoffs in S3 from
[Show spoiler]The Terminator Russian henchman, to The Faculty, to a Bond movie villain base knockoff. The show has simply become a derivative of itself. Let's emasculate Steve even further. Zero chemistry between Nancy and Jonathan. L still slipping into and out of broken English. Any sense of adventure is gone now. I really don't think there's much to like anymore.
My only real takeaway from S3 is that Sadie Sink (Max) is going to be an upcoming television/movie star.
