Fun as a fan, good story and great feeling. The feeling that feels like the biggest argument to recommend the game. One can do such crazy stuff and he moves so incredibly smoothly, that bit nail them to 100% The camera may get a little skewed sometimes, but it's just a side effect of having free rein there.
What is negative in my extremely humble opinion is that it can become a bit monotonous, the fights are quite similar.
And the buildings in Manhattan will soon become quite large and anonymous.
But the whole is larger than the sum of the parts, and it is just right with nerdy side gears, comic book references and help topics that anyone can start and think it's fun.
