No spoilers: Went in expecting it to be the same Justice League (2017) filled with random additional footage. I had been disappointed by Snyder in Batman vs Superman and didn’t expect much here.
I am happy to say that Snyder’s vision of Justice League is epic. The best thing is that this is a compelling superhero universe that has a distinct tone to the Marvel one (which is also enjoyable but you don’t want more of the same).
A much more impressive villain, much better individual hero story arcs (esp. Cyborg) and a JL origin story that makes you want more. I hope WB give him a chance to make JL2 and 3.
