Even without “Martha,” Batman v Superman is, in our mind, the worst of the DCEU films because of its wasted potential. Zack Snyder put everything DC fans could want into a single movie: Batman, Superman, Wonder Woman, Lex Luthor, Doomsday, and more, but it was just too much, too soon. Maybe if it came out later, when we knew these characters better, it would’ve worked better. But here, early on in the DC saga, it’s just a mess.
