Batman V Superman: 10 Mistakes It Made That Justice League Must Avoid

Batman v Superman was heavily influenced by The Dark Knight Returns and The Death of Superman, two comic-book arcs that are arguably the best representations of their respective characters. Stories like these, that provide some of the best source material for filmmakers to adapt, deserve to be treated better than they were in Batman v Superman - squashed down, chopped up and forced into a single movie that already had too much going on.

If these storylines fit naturally into the film, perhaps it would've fared better - instead, it appears the filmmakers tried to force them into a plot where they didn't belong, rather than including them as natural elements from the start. For example, why did Superman need to be the one to kill Doomsday with the Kryptonite spear? Why couldn't Batman or Wonder Woman - who would both be unaffected by the green rock.

As a result, Superman's death felt unearned, and wasted a great comic-book run which could've been explored fully in a different movie.

So, if Justice League is to take its cues from a powerful slice of source material, the film should respect that - don't force in comic-book storylines that don't fit. This weakens the plot, making moments like the Death of Superman - which should feel pivotal - feel forced. Justice League must focus on crafting a great story in its own right, and if a defining comic-book arc can be slotted neatly into that story, then great!
