Man of Steel, BvS and Justice League fell flat because Zach Snyder is an awful director. Wonder Woman showed that DC can make a good movie that isn't centered around just Batman. Hopefully now that he is out of the picture permanently, things will change for the better.
I'll disagree strongly.
JL's biggest faults came after Snyder left the project. MoS was the most "purely Snyder" movie in the DCEU and it's easily the best, IMHO.
And as has been mentioned on this thread, the Extended cut of BvS is head and shoulders above the theatrical cut, and those cuts almost assuredly came from the studio and not from Snyder.
I think it's the attempt at course-correction they did in Justice League that really dug a hole for them. I wish they had just stuck to their guns with Snyder, but it seems like WB can't handle even a little bit of criticism without trying to change everything they're doing.
