Liked the movie. Lot's of awesome stuff that we've never seen before.
That being said, Snyder has to go. The most popular superheros in the world need to be appealing to the general audience and even critics, not just DC fans. A part of me wants this film be a great financial success. Another wants it to be a financial disappointment so WB has no reason to keep Snyder anymore.
I think keeping him would be more harmful at this point. Think about the message WB will be sending if they settle with a mixed-bad reception but financial success: We're all about the money. Do we really want the DCEU to be seen as the next Transformers? do you want the DCEU to be looked at as a joke? a lame attempt to have a Marvel universe? or do you want these icons to be respected and admired by most people?
I really really hope they make something about this. Last time they changed the screenwriter, now we know for certain he wasn't the only problem. As much as I like MOS, Snyder should have been gone after it, but WB seems to be run by morons sometimes. I mean look who's the screenwriter for WW. Look at his work, all mediocre-bad films. There's absolutely no way I'm going to be overly excited about WW for that reason, even with Patty Jenkins on board. I'm expecting it to be a critical failure and a disappointing film. Next thing you know, the same guy is also writing Lobo...really? you handed him another property without knowing how good-bad WW is? FFS...
If you want to hire mediocre filmmakers then you better have a Kevin Feige type of person keeping an eye one them. Until then, get the best filmmakers you can, especially when you're going for a director oriented universe. Now think about the way you would feel if WB announced Ben Affleck will be directing the JL, or George Miller. Would you feel angry, or relieved?
I think the answer is obvious for most people. I like Zack Snyder, I really do, but as long as he keeps making decisions because "it looks cool" and because "that's how it was in the comics" he should go back to direct lower budget CBM's. When he understands he's in charge of icons that are meant to appeal to everyone; men, women, parents, grandparents, etc. and he proves his skills as a story teller then let him in charge of big properties. But for now, if WB decides to keep him, which I'm thinking is very likely, the DCEU is pretty is pretty much doomed.
