We all know Justice League (2017) was a major failure. Trailer scenes were cut, plot holes everywhere, underdeveloped characters, unnecessary comedy, terrible cgi, and a missing essence, resulting from the beatdown, editing and changing done to the director's original vision.
Zack Snyder's Justice League exceeds in not only fixing these issues, but presenting a full story, given time to develop and unravel, as any great narrative should. Plot holes are filled and explained, characters are given to be understood and explored, comedic scenes that were forced in were removed, and the ones that were originally intended to be present, were improved, resulting in a non-cheesy approach. The cgi was fixed and the colors were restored. Overall more of this world was shown and explored, and the possibility to a well deserved continuation of Zack's story has been opened. This is a must see restoration, for those who stood by it, and those who lost faith or interest in the DCEU.
