Snyder's Justice League is definitely everything that DCU fans deserved in 2017. The movie is a complete masterpiece, it builds characters individually without rushing the story or even mixing ideas and losing their essence. Everybody has their time in the screen and play a role in the team, an active one.
The movie is as dark as the comics is. It is divided in parts, like chapters of a comic book which makes us want always more. The closing is well designed and leave us the feeling of a big thing to come, although we still don't have any news about a sequel.
As a big fan, I hope DCU go back on their decision to continue the movies without Snyder.
