Storm it Swimingly, time to bring out my lvl. 100 OPINION.
I honestly dislike the bastardization of Vamps and Lycans in Twilight, haven't read it but have seen enough publicity to not be interested. The crowd that books like Twilight are aimed at are clearly not the mid-twenties, wrench turning, Booz drinking, cigarette smoking, metal head nerds (please tell me that's an actual crowd and I'm not alone) It's aimed at young women who like romance and drama and shiny sparkly things, these young ladies (and occasionally men) are just as big of fanatics to their genre as we are to ours.
As for The Hunger Games, I haven't read those either but I enjoyed the movies to an extent and I find little fault in them. They have a similar fan base as aforementioned Twilight but with a smidge more action. These are YA books to be taken at face value, people like them, people don't. What can we do about it? Nada. Love them or hate them they are still better than sitting in front of a tv and drooling all day.
...Twilight still sucks IMO though.
