Ok im a Marvel guy never really ever into DC. But I watched the movies to see how they were, and I have to say if you watched the Justice League but have not watched the Zack Snyder's Justice League make time to watch it. But be prepared the Zack Snyder Justice League is 4 hrs long. But I think the length of the movie is worth it for the content of who's in the movie and the new characters brought into the DC movie world.
