I actually agree, Goyer probably is the weak link when it comes to Snyder's more recent DC movies and also, I suspect, the reason I didn't like Man of Steel very much. The guy did write the very solid "Dark City" back in the day, which is why I don't want to dismiss him as talentless entirely but I think between him, Snyder and Terrio he's the one who contributed the least to what I liked about BvS.
There is a lot of really neat stuff in Batman v Superman. My favourite probably being its interpretation of Lex Luthor who I consider the perfect supervillain for a post Gamergate world, part Mark Zuckerberg, part Milo Yiannopoulos, part Elon Musk. This smarmy rich nerd with a god complex who ends up creating an uncontrollable monster because he's obsessed with killing an immigrant. Hell, what better bad guy could you even have in 2016? Even if his performance is very over the top, he's such a great depiction of an evil capitalist. He hires a PMC to massacre civillians in Africa, he pays off politicians to get access to state secrets, he uses the media to shape people opinion of Superman, he's fantastic. Or how, it questions what the archetypes of Superman and Batman represent in the modern world. I love how they focus on this conflicted Superman, struggling with his own responsibility and whether he's a danger to the people on earth, simply by existing and how he feels guilty for being the one who brought Zod to Earth. And how they draw that parallel with him as an immigrant, and the invasion as sort of a 9/11 analogue, it's really clever. I love how it makes Batman basically a bad guy for most of the movie, not excusing or glorifying his vigilantism and paranoia the way the Nolan movies do but actually showing how it turned him into this bitter, violent man who abandonded practically all of his formerly noble principles to the point even Alfred starts to lose faith in him.
I just think there is something very artistic to the gravity he brings to these conflicts. When he has Batman and Superman face off against each other it doesn't feel like it's just two dudes in costumes having a fight, it really feels like you have this mythical conflict play out. He doesn't take away from these scenes by shoehorning cheesy one liners into them or filming them in an overly matter of fact way, he makes the big and bombastic and larger than life. He just creates this world that seems slightly more fantastical and mystical then ours and then uses it to engage with some very real themes and conflicts. I wrote it when writing about his Watchmen adaptation in a different thread, he adapts comic books like he was DeMille adapting the bible.
Oh, and I did really like Logan! I don't have all that much previous investment in X-Men and its characters, but I lovesJackman's and Stewart's performance, I liked the western inspired narrative and visuals, I did think it had a few things to say that I very much appreciated... I felt that towards the end it got a bit cheesy, I get what they were going for with the kids, and passing the torch onto a new generation, it just felt a bit silly to me, with the kids being as young as they were. It was by all means a very good movie. I didn't appeal to me stylistically quite the way BvS did but it's definitely something that stands out positively in its genre. Another recent superhero movie I really liked that Into The Spider-Verse, even though that was obviously a much more light hearted affair.
