The movie is a take on the comic and sitcom story, Justice League.
It is very entertaining and has great CGI and audio. The problem arises with the story. The story lacks in explaining the origins of a lot of characters and is very empty.
The movie is a base for other superhero movies to come so a very small part of justice league's adventures are portrayed here.
Great if you want to go out for a casual movie night, but if you are really interested in the story itself, you'll be better off just reading the comics.
Try watching the movie in imax 3D. The visuals look amazing this way.
I give the movie 3 stars out of 5. Good on entertaining visuals and fancy superheroes but lacks in story and narrative.
