Maybe I'm wrong, but I thought the reason they introduced the hunks later was to give the joes who don't have the look to immediately attract the girl to have some time to get to know the girl and to use their charms to attract her. But they introduced the hunks later, because just as in real life, joes have to compete against the hunks for girls all the time. It kinda suck that Melana picked a hunk over a joe at the end. But that's her choice, right? It seems like she picked a guy she can fall in love with instead of trying to delude herself and pick a guy who is rich. I think Melana was in a no win situation for those people who are looking for faults in her decision. If she had picked Adam, people would say how shallow she is for picking a rich guy who she is obviously not attracted to. And since she picked Jason, people are now complaining how she is shallow for picking a guy just for his look.
