Justice league is one of the best superhero movies of all time. I just completed this movie and I found some pretty interesting details like cinematography character introduction music background score and obviously the CGI. There is no hesitation in saying that this justice league movie given to us by Zack Snyder is way better than the one offered by Joss whedon.
It was really good to see e the details that were missing in the previous film and also the introduction of flash time paradox. Superman in the black suit and darkseide look dope. My personal recommendation is if you haven't watched this movie just leave all the things and go binge on it. Your 4 hours are actually worth investing time on this masterpiece.
