The unfortunate demise of Zack Snyder's DC superhero universe has made it hard to know what to expect from forthcoming hold-over movies such as "The Flash," "Aquaman and the Lost Kingdom" and the just released "Shazam! Fury of the Gods." New DC head James Gunn has spoken highly of all three films and has vaguely indicated that they each have roles to play in what his plans are going forward. Whether that's true or just studio speak remains to be seen.
