The plot, hideous character models, outright annoying stealth missions and the obnoxious revamps of MJ and Black Cat drag the game down quite a bit for me. I seriously could not stand this generic stronk independent woman version of MJ. She's like a worse mashup of MJ and Norah Winters from the comics.
Webslinging is good but doesn't feel as fast as I want it to at times, and I found the more challenging combat scenarios to be out and out frustration.
I definitely enjoyed Arkham Knight more as far as the world design, overall aesthetic and great combat goes. Some of the cutscenes in Arkham Knight have absolutely fantastic camera work and the characters just look fucking great. It's a shame the plot is so bad near the end. Like it's predictable borderline dumb stuff, with the exception of the scene of Batman's psyche overcoming the Joker infection.
I'd give Spider-Man a personal score of a 7 out of 10 and Batman an 8 out of 10.
