I don’t understand this about it being unoriginal. Having a reality show where contestants kill each other is not such an unusual idea that two people cannot come up with it independently. In fact, there’s a Doctor Who episode with a similar premise. In my social circles, many accuse HG of ripping off some Japanese story called Battle Royale, which apparently has the same premise also. It is a fairly common premise, and in that sense it is indeed ‘unoriginal’. However, I think the series (books as well as movies) simply resonates with teenagers, and they’re not really borrowing their plot from anything else. They’re just taking a similar idea and running in a different direction with it.
I’m the opposite of some on this thread- I LOVE reading into things. Whether or not I’m right about intent, analyzing fiction is fun!
