WTF did I just watch?

Seriously? What was the point? What happened to the professor? What happened to the girl? Her fiance? The rock through the window? Why did it end this way? This isn't even an ending. Did they run out of money mid stream and just decide to end this POS right then and there? Did the broken window put them over their spending limit? The glass get in his eye and they had to stop the film? Was this some kind of sick joke? While a steaming pile of pretentious bullshhhht.
