Note: Not going too talk about art style or graphics, just story mode.
I recommend people to watch the story mode. (with or with out the in between gameplay). The dialogue has some good comedy and seriousness between the characters. Voice acting is mostly spot on with the characters. However their is no music on most of the cut-scenes, mostly the music plays when your playing in story mode vs the cpu. The fight scenes are done decently, our favorite takes place in valkanda. My brother and I might sound crazy when talking about this but it is actually far better than what could have been. It's not maybe an award winning story, but it sure isn't trash (far from it).
Okay I am going to admit that I did not like story mode at first, but that was me expecting too much for what it is. After completing it we thought not bad. I showed the story mode to my older sister with out the gameplay just cut-scenes, who is a marvel fan and only has limited game knowledge. (she knows street fighter, x zero, Dante, does not know who Chris or nemesis is or where they are from). She Liked the story and thought that it is much better than she was expecting. We did not show her any story trailers for this game, she came in completely blind.
Story mode is 3.5 stars good, but not excellent. A good story to have at movie/popcorn time.
PROs: Good dialogue and Interactions, voice acting, some fight scenes
Cons: Not much music during cut-scenes.
