This is probably the most functional edit Justice League that I've seen, and that's including Zack Snyder's Justice League and the Theatrical Cut. You've done an excellent job of cutting out all the dead end sequel set ups, while maintaining the tone Snyder intended. However, I think you over-corrected a bit in your attempt to get the film under three hours.
The biggest problems with the story editing here are that characters like Wonder Woman and Desaad have had their introductions cut, while characters like Aquaman and Steppenwolf no longer have understandable motivations. I understand why you cut the Aquaman/Vulko scene and the initial Steppenwolf/Desaad scene, but the movie doesn't work without them. As it stands, Aquaman disappears from the movie after his initial appearance, and Desaad just shows up with no explanation of who he is or what his role is.
As I said, I understand that you were trying to streamline the film, but I honestly don't think a functional version of this movie could be less than three hours long (to be fair, that is a problem inherent in the script).
Those issues aside, however, your editing is very smooth and seamless. You were able to trim down overlong sequences and skip past unnecessary scenes in a way that felt very natural. The best example of this is how you used Batman's "doesn't mean I'm wrong" to skip past the awkward song for Aquaman. The way you cut Darkseid's final conversation with Desaad was also masterful; it felt like that was how it should have been edited the begin with.
Also, by reintegrating the "Everybody Knows" title sequence (the best part of Whedon's version), you were able to give the beginning of the film a lot of much-needed energy, as it now feels like there is a cleaner transition from "Superman is dead and everyone is sad" to "alien invaders are coming and we need to prepare." That was a wonderful addition.
I have more notes and comments, but this review is already too long as it is. This was an enjoyable watch, and I think with another edit that doesn't shy away from letting the film be three hours, this could be the ideal version of JL.
Quite possibly one of the best cuts of Justice League in existence, and that's not hyperbole. The "Wonder Woman vs the terrorists" scene and "Barry Allen saves Iris West" scene were great scenes in isolation, but did nothing to advance the plot and ultimately were not missed in this cut. Removing the Anti-Life Equation removed a giant plot hole, and again it was not missed.
I do miss Cyborg's vision of Darkseid, the little ship tease between Bruce and Diana, and Diana's interaction with Alfred that docked a point in the enjoyment scale for me, but overall this version of Justice League was just frigging awesome.
Not much to say. Spence made a great, digestible version of the film Zack Snyder originally set out to make (with some ideas from the Theatrical Cut, but hey, they were good ideas). If you're curious & don’t have half a day to waste away, definitely check this edit out.
The Spence edit does a wonderful job of balancing both the TC and ZSJL cuts. The scenes from the TC are CC'd seamlessly as it is not noticable during the everybody knows montage. Best thing about this cut is that it removes all sequel baits, especially now at the time of writing this review, the DCEU is stepping away from the Snyderverse. So this cut serves as a shelf replacer of sort for current continuity. While some scenes from both TC/ZSJL are missed, like WW vs terrorist, Barry saves Iris, and Aquaman sits on the lasso, they were neccesary for pacing and to keep the runtime under 3 hours. Which is perfect for what should be the Justice League's first film. Another thing that I liked from this edit is that the full ZSJL ratio is kept during action sequences and widescreen throughout the rest of the film creating an IMAX theater feeling. So overall I'd recommend this edit over others and it serves as a shelf replacer for me. Although one thing I would add is the Superman/Flash racing scene as a post-credit. I feel like putting it at the end wouldn't disrupt the hopeful ending or the tone of the film as much and it would show Superman just talking to another leaguer.
This is the best version of ZSJL edited down to a reasonable runtime that I have seen, and I would expect nothing less from this amazing editor! Top technical quality all around.
I am a big fan of ZSJL, so I actually love the longer original just fine for a full day binge watch, but thats now always what I'm looking for. I understand the cuts made and in this edit they aren't missed, and to hit a more reasonable runtime, I think the wisest choices were made. Well done!
