I agree with this a lot. The DCEU has problems, like I'm not a shill or anything, but when people treat the MCU as if its perfect it makes it impossible to discuss the DCEU. Like, I've been called a liar for saying Hulk 1 and Cap 1 were probably flops, while citing proof, because so many MCU fans insist their franchise has never had a flop. It makes it really hard to have a good faith discussion on these issues.
I still contend that the DCEU, warts and all, is one of the great movie franchises of all time, but people can't see this because they are constantly comparing it to the MCU.
