Finally finished it...
Very fucking good: 8.5/10
Joss Whedon can suck my dick. He really did ruin this movie. I'm sure he was left with a mess, but he fucking made it terrible and contributed to the destruction of the DC Cinematic Universe. All the stupid shit from JL (Flash fall-raping Wonder Woman, Martha calling Louis "thirsty", the weird almost relationship between Batman and WW, etc) was Joss Whedon. Apparently Aquaman sitting on Wonder Woman's lasso of truth was Whedon too, and I did really like that scene, but it's gone.
All the crap with the family in Russia where Steppenwolf is is all gone thank god.
This cut makes every single character better:
Flash - he is still a little "scared", but he doesn't have to be talked into being a hero (although I like that scene, the character is stronger without it), and there's a lot more of Flash in the movie, and a couple of really awesome scenes where he shows off his powers. He still is very funny, but without being just a total pussy. The scene where Superman is resurrected and Flash runs at him and Superman sees him and then goes at him, that scene is extended and Flash actually takes a try to push Superman down.
Cyborg - I just hate the character, but he is WAY more fleshed out, and he has a lot more of a prominent role, and a lot of what he does is explained.
Aquaman - a bit more of him and his background
Wonder Woman - way more scenes with her, including multiple prolonged more scenes, this is the fucking Wonder Woman we needed, fucking badass warrior. Just fantastic. Her scene in the government building when the people were going to blow it up. Much longer, much much better. She's just fucking awesome. I would say best female action role ever, surpassing The Bride from Kill Bill.
Batman - actually kind of less Batman, and less of him and Alfred plotting or planning.
Superman - black fucking superman suit. YES.
Steppenwolf - Not kidding, they actually made him a compelling villain. In the original, he was a CGI mess of stupid. This one, he has motivation, intelligence, etc. He looks way better with this kind of living metallic armor. Multiple interactions w Darkseid.
Parademons - they didn't just seem like little henchmen (ie, Ultron's little robots), they were legit badasses, powerful, and menacing.
Themyscura - (however you spell it) a MUCH longer scene when Steppenwolf takes the motherbox. Really, really well done. Insanely better. Fucking Steppenwolf was throwing horses around, it was awesome.
Opening scene explaining how the motherboxes woke up - fucking awesome.
The scene when it shows the first time Darkseid failed to conquer earth, fucking fantastic, Zeus, Green Lantern, etc, all fighting. It was such a cool scene I would have been fine if the movie ended there. Was the barbarian human anyone in particular?
The epilogue .. this is the only part of the film that was weak to me. When I rewatch this, I'll probably stop it when it shows the Epilogue title screen.
....
This was WAY better. It's fucking long but worth it. Good job Zach Snyder. Fucking bravo. Fucking great movie.
