I was apprehensive about this, especially after the critical response to Whedon's Justice League in 2017. I personally enjoyed it immensely and the 4 hours flew by. I've seen reviews stating it's "A Mess".... I disagree.
It is by far the best DCEU film and much better than any of the Marvel Universe films I've seen. Character development gives the Heroes more depth and the story for me made perfect sense. Just feel sad that "Justice League 2" will never see the light of day...
