Superman was the best Superman I've seen in decades. It wasn't that good. It was awesome for a DC movie but Superman the character sucks.
Even partial resolutions made no sense. Luthor's plot made no sense. Luthor's tech seemed absurd. Dorkly's latest video on Luthor's assistant really provides a humorous look into Luthor's problem. Guy could make himself bigger than Superman by solving world problems. Instead convoluted plans.
Green Lantern's character caught me by surprise, but apparently the comics went in that direction. Nathan Fillon, love the guy, didn't work for me. In fact, the side heros of the Justice "Gang" felt so hollow.
Oh and can we get to the part where Luthor manages the video recovery, translation, confirmation in what a day? It is like Gunn had a plan on turning Superman heel and was doing a decent job early on, but then decided to sidestep it.
Finally, the rift, it kind of matters, kind of doesn't, kind of does again. Also onpy tearing a portion of reality, and only so much. Anti-proton river? The science and coherence in Lego Batman was better. Please, don't science if you aren't going to try.
The Gunn feel was there at moments, including a particular sequence that seemed taken from GotG III. But overall, it was a weak influence. This guy made you want to tear up because an otter died... and Superman mostly felt like a dimensionless cartoon.
Nonsensical, inconsistent, one dimensional, and inorganic with the humor.
