The Justice League takes off from the exact same point where Batman vs Superman had ended. So Superman is now dead and it is upto Batman to assemble a team against a powerful supervillain. The thing with The Snyder’s cut is that it adds a lot to the characters and their origins. For eg, Flash and particularly The Cyborg are the backbone of the film here and they get adequate screentime in establishing their characters in this 4 hour marathon that passes like a breeze. Also the supervillains are much more powerful here, a criticism which is countered from the theatrical cut. Also Batman and Wonder Woman are given better prominence than before. All this contribute in making the movie much more substantial and a superhero movie that we deserve. This being shot in the imax ratio of 4:3 would have worked wonders had it released in a theatre. The shots and VFX deserved a big screen to truely have a wholesome impact while witnessing this saga. On the downside, the screenplay slows down a bit in the middle, and you get a feeling of wanting the writers to get a move on. But these are minor blips and the movie is well back on track in a breathtaking finale! Excellent screenplay!
