I've been playing this for two weeks now and its actually fine. The graphics are fine. I liked how they incorporated the infinity stones into the gameplay. The story mode is like a movie. Though some of the locations could have been better. While the hud and interface design are ugly looking similar to SFV.
Marvel's roster is fine. The only ones that I don't like as playables are Ultron (Ultron Sigma is already the boss) and Dormammu. The lack of mutants is unfortunate. This game brought back memories from my childhood but I definitely felt the lack of the mutants. They also could have added Ant-Man and Star-Lord, since the game is MCU inspired.
Capcom's roster is a miXed bag. I felt like it needed more Street Fighter, Resident Evil, Darkstalkers and Devil May Cry. I enjoyed using Stryder, Jedah and Morrigan especially I don't have them in other ps4 games. There should be a modern Darkstalkers game and a 3d action adventure game for Stryder.
Over all, its a decent fighting game. Though I would like to see a fighting game just with Marvel characters neXt time, a Marvel Super Heroes game in current gen consoles.
