Granted, I don't mind Mendes at all as a person...she's not drop dead A-list gorgeous, more like "I'd see her type walking down the street and be like, hey, she's kinda attractive." Though it's obvious she was brought on board to show off the goods, that's it. Roxanne had no other reason to be there but to say, "look at my boobs, look at my curvy ass, etc." Though they did allow her character to be just as goofy as the rest of them, so she wasn't exactly the straight man/woman in this. The magic 8-ball, the constant glasses of wine, and so on.
