You know, I actually liked Brenner's "coming back alive" arc. Not exactly that one arc itself but the plot that came along with it. His real death in S4E8 was so much more realistic and emotional, as he finally fulfilled his job in the series and his character was complete when he passed away. Probably an unpopular opinion, but Brenner's death scene was my favorite out of all the death scenes throughout Stranger Things. It had the perfect amount of realism and emotion. It was perfect.
