Lady Gaga and any other celebrity would give a ratz azz about Spencer... (SPOILERS)
But Lady Gaga isn't M. Night's daughter... Lady Raven is! Therefore, screw the people who will say these decision makings and actions are unrealistic, it's a vehicle to showcase his daughter, and that's most important!
Seriously Mr. Night, couldn't you think of a better script to show off your daughter? LOL! During the movie, I was curious if she was a real singer, so I looked her up and found out she's M. Night's daughter. When I told my wife, everything made sense to us. LOL! Why in the world is this pop star risking everything for Spencer? "Lets go to your house...," was Rambo level. It would have made sense if she was retired special forces. LOL! A normal person would have dropped them off, then call the cops.
Unless, I'm an idiot and I missed something. Did the wife and Lady Raven plan it? For her to be forced to make a decision between Spencer or take the Butcher home in a Limousine, and for her to recommend going to their house? Was that all planned? I'm pretty sure it wasn't.
