I had a blast watching this. But if there's any chance that Snyder does a follow-up film, I hope he ditches Chris Terrio. To me, Terrio's screenplays are just too much of a cluster**** (and with plenty of subpar exposition and plot progression).
Personally, I'll watch this Snyder Cut in the future by splitting it in two parts - right around the midpoint, leaving both around 2 hours each. The first half ends with that new hallway reveal after Martha and Lois have a chat at the table; and coming right after the JL decide to revive Superman.
Heck, if WB had let Snyder finish in the first place, they could've split the film this way for theaters and just released the first part in 2017 and the second in 2018. I think the advantage with that would've been to have an entire first movie without Superman's return so that his BvS sacrifice would've had more time to breathe and carry more weight.
The first part would've already included a big battle between the JL and Steppenwolf (plus Parademons). Then just end it on the Supes hologram (or something along those lines), and start hyping his return in the buildup to the second part being released.
Oh well. Just glad this version got finished and released. I dug it. Some enjoyably silly, over-the-top fun to be had throughout all 4 hours. And I love that Snyder stays true to telling a story that *he* wants, rather than worrying about pleasing anyone else. Bravo!
