Michael McKean (Chuck) such a complex character *spoilers*
He was so much fun to watch with his multi-layered personality. You felt empathy for him, you thought he was a real jerk and hated him too. I am going to miss him as a regular character because he was so much fun to watch.
He’s one of the best character actors ever! In a way, I am glad in a way that they ended his story because if it had gone on any longer it would become less interesting, although, They put so much work into developing him that he could have still been very useful to the plot. It’s cool that he will come back in flashbacks at least. I wonder if they killed Chuck off because Michael wanted out?
