Ending explained #9

Rating: 10/10 (17 September 2018)

There were 8 explanations for the ending on IMDb. I have one more.
The whole movie is about balancing between passing Hollywood fame and meaningful Broadway success.
So yes, Sam looks up and sees her father really flying. This underlines the fact that this is a Hollywood movie we are watching, not Broadway theatre. And in Hollywood movies you have to do this stupid lame stuff for mass audiences, because you are not in artsy and critique driven Broadway.
And yes, you were tricked into watching something you thought was piece of art or new "super-reality" with real blood. But then the rug gets pulled under your feet, just as you thought you would just once witness a sad but true ending with suicide in a Hollywood movie. But no, it's just another happy crappy ending.
Great stuff!
