You must not know must about the movie industry...
$150 million dollars (which they aren't going to make anyway) is not a good thing when your film cost between $200-255 million. I don't know what universe you're living in where that makes sense, but it ain't in this one.
That is a loss, plain & simple. Sure, on the back end they make make a little more due to merchandise & eventual DVD sales, but this is a poor ass box office performance.
No amount of denial is gonna change that.
And putting TASM 3 against Superman/Batman & Captain America 3 is murderous. Point blank, if they stick to that slate they are going to get slaughtered. There is no way Spider-Man (at this juncture) can compete with two juggernauts of that magnitude.
