That's cool, but without Snyder at the helm, I'm going to bet a lot of people are going to be let down by the visuals of the next Superman movie. Say what you will, but Snyder's films had the best flying Superman ever. There was weight to things. The way shots panned and zoomed really sold the sense of speed and strength Superman has.
In comparison, Shazam came out afterwards, and it lacked that same visual punch. It's not just the effects studio. The director and cinematographer get to specify how things get framed and lit, and Snyder has shown that MoS, BvS and JL's flying sequences that he has a keen eye. We see it in Sucker Punch, and to a lesser degree (ironically) in Legend of the Guardians.
Anyway, I just wanted to say that. I'm glad Cavill can stay on as Superman. I just think it would be a shame to regress on the visual side of things.
