Who are you arguing with? Who talked about story (other than the developer)? It looks like Hulk UD, and by that I mean that they basically took the destruction and the moves from UD, but replaced Hulk with some hooded shapeshifter who can wield guns and take over vehicles. Hulk UD was a favorite of mine, so hey, I'm alright with it. Judging by your reaction, it honestly doesn't seem like you are.
As for realism, that's not even an issue. But taking down an attack helicopter with a flying body is pushing it. Tossing a car at it, sure. It's a bit like comparing Burnout and Gripshift.
