My theory as to why s4 Flash was bad is because of Iris taking on the leadership role when she just sits back and lets others fight the bad guys. Barry's personality after encountering Thinker was too obsessive and stalkerish until they defeated him.

Also, characters were written to be so frustratingly stubborn. It was the same for the other season 4's. Supergirl is awful with Ben Lockwood/Agent Liberty saving the season. Arrow s4 was awful but Damien Darhk saved it. Unfortunately, LoT is having the same issue. I found the 3-4th episodes underwhelming. I personally think LoT did well in seasons 1-3.
