Justice League: 10 Things It Should Have Done Differently

One thing Justice League failed miserably at is its sequel setups. There's a fine art to this and lessons to be learned from the likes of Amazing Spider-Man 2, which collapsed beneath the weight of its references, Easter eggs, and villain teasers.

Nobody likes to see universe building in a contrived way, but posing mysteries, asking the audience questions and foreshadowing the emergence of their favourite villains in a nuanced and organic fashion can do wonders for a franchise.

The problem with the Legion of Doom-teasing post-credits scene is stakes. It features Lex Luthor and Deathstroke, both of whom are mortal, albeit highly resourceful villains. Do they really stand a chance against five god-like beings (perhaps more now Watchtower membership is open) and the world's greatest detective?

In order for this teaser to be effective, it should have offered a hint of who else is going to be on the team. Luthor is the brains of the operation and Deathstroke has proven Batman's equal on a number of occasions, but they're going to need some heavy hitters on side to stand any chance against Superman and Wonder Woman.

There's no sense of a bigger picture being woven in the background, a larger threat looming overhead. Darkseid, who should have been lined up in a Thanos-like capacity by now, gets nothing beyond a passing mention.

There are no burning questions the fans are desperate to have answered in the next movie, no hint of a bigger threat on the horizon (Luthor and Deathstroke are smaller scale than Steppenwolf), and few clues about what's next for the main characters.
