While I feel the writing has been pretty good and within character, I felt Izel and Sarge's character arcs were a bit wasted. They were certainly finished but I was left with many questions about their motives, their histories, and the why. A good villain is one that you can understand their goals and motives (see Thanos, and Mysterio recently for Spiderman FFH). Why should we be scared of the Shrike and the people through the portal/monoliths?
Dialogue was pretty solid between the cast. Their chemistry is basically second nature at this point. I wished they would create an arc for Daisy but oh well. I hope it's not money/contract related.
The action and CGI felt a bit low budget for a season finale. The special effects for season 5's finale was insane! It felt like they blew most of their budget for the season opener and first half of this season.
I'm still grateful we got a season 6 and one last season to go.
