Zack's cut may have been over-extended but oh boy! What a great ride it was! The story made sense, the pacing made sense, the villains looked and felt threatening! Cyborg's and The Flash background stories were exquisitely delivered and much needed.
The only thing is that it should have ended sooner, the apocalyptic scene at the end felt like a filler more than a set up for the next film.
Spicy take! Was Joss Whedon sent by Disney to destroy the DC Cinematic Universe within? Don't let that guy direct more DC movies again, he sucks.
