Spoiler Alert!
Justice League is an absolutely amazing movie. I love almost everything about it (save one particular dialogue which I didn't like). But really, this is got to be the best movie of this year.
The direction of Zack Snyder with his use of darkness and light to create the environment, I had appreciated in the movie "Batman vs Superman" too. This movie is brilliantly directed and there is not one dull moment. I actually was surprised when the interval came and I didn't appreciate the interval too :p
The heroes have a distinct Christian character and appeal. The Wonder Woman calls herself a "believer", Batman uses Jesus name frequently in the story, the Flash is a nice comic Jewish kid, and well Superman, is the most Christian of them all, a sort of Christ like figure, who comes back from the dead this time to save his beloved earth. The comic moments of the movie are hilarious, the villain is powerful but not invincible, the emotions and the sparks of the characters is compatible, aquaman is true to its form, and the movie is like the cyborg says, "boo yah"!
The story line is simple, and I prefer it that way. Who needs subplots when you have Gal Gadot and Henry Cavill?
Make this movie the one to be seen.
