Third time trying to slog through this shiftiest

I am trying... and god knows why? boredom? to slog through this shiftest of a movie. The main character Sloane is about as generic as you can get. Nasty, selfish, stupid, self involved and not funny. Does not really bring a lot to the table as a main character.
The writing is terrible. It was like a cut and paste from all previous crappy movies. And hey, I do like crappy movies, but this one is just cringeworthy at best.
