Hey, the movie is turning out basically exactly as I expected, so I'm still excited to watch it! Low expectations ftw. I really doubt they can afford to drop Snyder just because of negative reviews though. It's still going to make a ton of money and it's a little late to stop production now. Unless they pull an Ant-Man on it.
The reason why I could see them take a hit and delay production to get it right is because WB has nothing else to fall back on. No more LoTR movies, and the Harry Potter spinoff is a big question mark at this point. They needed everyone on board this universe they are developing, have successful movies, movies that make tons of money. Also they have a huge advantage over Marvel Studios, they own DC completely so they can use whatever character they want. It was time to finally get this running, but having 2 divisive movies in a row is not good at all. I mean not all of Marvel Studios movies are good, the Thor movies and the Hulk movie with Norton aren't good at all. But the movies that mattered like Iron Man 1 (being the first) and The Avengers (the culmination of years of build up) they got everyone on board those and after that it was smooth sailing from there on out.
Movies that are completely average like AoU even get good critical reception just because. I mean it even happens with the CWverse, I enjoy Legends of Tomorrow but looking at it objectively it's a very average show but because it's setup in a established universe it's better received than it would've been otherwise.
of course if it makes a lot money then it's all moot, because that's what matters in the end.
2nd weekend is gonna be VERY telling.
