You can like Superman and still enjoy different takes. I like Red Son Communist Superman, too. Personally, I feel like having him return as a disciple of Darkseid could’ve lent itself to some heavy subject matter. Case in point: that idea of the world losing hope without Superman. What if the Justice League know he was the mystery man leading the Apokoliptan Invasion, but no one else does? He breaks free of whatever brainwashing they’ve used on him to that point and then the JL are faced with a moral quandary: do we let people know that this was Superman? Do we hold him responsible? Did he know what he was doing? Has he suffered enough?
There are all kinds of approaches you could take that would fit within the narrative created by MoS and BvS. The problem is, it seems like those of us who enjoyed that take were so in the minority that WB saw fit to throw the baby out with the bath water in favor of something more audience friendly, which is fine, and, like I said, I actually enjoyed a great deal of JL, but, to me, I feel like I’d take consistency and a director’s artistic vision over a movie that was, essentially, created by a committee of studio executives.
