My favorite things are not limited to Marvel or New York, so I don't think it would be necessarily helpful to your search for something to enjoy here. Video games, reprogramming computers, basically not leaving the apartment unless I have to. That's not to say that there aren't lovely places in the city, but most of my time is spent at home. I did stroll through The Cloisters the other day. I prefer it to Central Park.
Why don't you tell me something you do enjoy, and I can offer recommendations from that?
