Three strikes, you're out?
Or in the case of Zack Snyder, five?
Regarding Wonder Woman, Sasha from the Schmoes Know podcast, which happened to have DC All Access' Tiffany Smith on, said she heard it from the same friend who heard that Batman vs. Superman was bad that Wonder Woman is a stinker as well. Sasha went on to note that she and her source are big Wonder Woman fans and were hoping for the best. The DC source/Sasha said, "I'm very disappointed in what I saw, and it seems like all the problems are the same problems. It's discombobulated, it doesn't have narrative flow. It's just very disjointed."
Now for Justice League, a rumor hit the net earlier in the week that states the Ben Affleck Batman movie production is getting pushed back a few months until Summer, which may be because Ben Affleck is still writing the script. However, Batman on Film theorizes it may have something to do with problems with Justice League, in which they hear is a "mess." It's further suggested that Ben Affleck may even want to bail on the DCEU because things are so bad, which is why Ben Affleck has been seemingly back and forth about doing the Batman movie.
Following the disappointment of Batman vs. Superman, Warner Bros. was said to have made changes by removing or downgrading the roles of certain producers and promoting Geoff Johns to DC Entertainment President and co-runner of the DC films with Jon Berg. I think Wonder Woman is the first movie Johns and Berg are fully involved with, so if things are still the same, it appears more changes will be necessary. The common denominator on all the movie happens to be Zack Snyder and his brain trust of producers which includes his wife Deborah Snyder, Charles Roven and Wes Coller.
Zack Snyder was also behind the lukewarm response to Man of Steel (director) and produced Suicide Squad, which got hammered by critics.
