Just finished watching this and I was blown away by how little depth they gave the bad guy. I don't know his name because they only said it twice. He makes his entrance shooting his two buddies and then saying he had to do it and that no one helped his family when he was starving. He then tells the protagonists mom she should just walk away, before shooting her when she refuses.
And then that just repeats the whole movie. He attacks people, and says he was poor earlier in his life. He also tells Madame Web to walk away. No flashbacks, no explanations, no monologues, no ideals. No depth. I actually love him as a character because he is so one dimensional and ruthless, closer to Jason Vorhees than Thanos. Its just a very odd decision from a writing perspective. Also he kind of talks like Tommy Wiseau.
Besides him the movie wasn't great. Feels more like it was on the writers/director than the on stage talent though.
He is Ezekiel Sims and the Wikipedia entry might give more background on the original character, although he has been chopped and changed so much he is almost unrecognisable.
The reason the character is so one dimensional is that they radically changed the story (why cast members have been so happy to throw it under the bus, as what we saw wasn't what they signed up for) and we'd have got more of his motivation. As the character is key to some of the big storylines and lore upgrades, he might have also helped set up future films. Instead they still seem intent on killing the franchise, which isn't necessarily a bad thing, because a Spidey-less Spider-Man fictional universe is a stupid idea, badly implemented.
