This song is incredible. Even just going off this one movie and this one scene, this theme song rivals the Avengers theme. It may not have the emotional impact and the longevity that the Avengers theme has had but if the DC universe was a bit more consistent and had a few more years, I could see Junkie XL's Justice League theme becoming iconic.
The film itself was pretty good, it has all of the same elements as the 2017 version so when watching it, I couldn't tell what was new or not (apart from the obvious) because it was mostly just pacing and the tone that was different. It wasn't trying to be Avengers 2.0, it stuck with the dark theme throughout.
It could have been half an hour shorter though, the apocalypse scene at the end could have been cut because I don't think it added anything. The Joker scene was a bit much, but I understand that it was basically Zack Snyder's tease at what could have been.
