Despite its flaws, Justice League is one of the most entertaining DC Extended Universe movies to date. In addition to the action sequences and the excellent chemistry among the stars, Justice League is filled with delightful Easter eggs and references. Some are in blink-and-you'll-miss-it scenes, but others arc throughout the story.

And they all work, because even though there are so many of them, they don't overburden the film. Zack Snyder and Joss Whedon did a great job from this standpoint, especially with the film’s brevity.

Obviously, there are major spoilers ahead for those who haven't seen Justice League!
