What ruined the Hunger Games series for me:

All the time those kids spend in an arena, just days and days, and none of them ever takes a shit.

I mean, novels never talk about people shitting, probably because it's just subsumed into ordinary life, but being in an arena with no amenities of home while other children try to hunt you down really would be exceptional circumstances that demand you discuss how they handle that.

Like, you'd have to wipe your ass (or not), and you'd have to make sure your hands were clean to eat food.

And, you'd have to hide your shit or bury it so that the others wouldn't see it or smell it and then find out where you are, or so it wouldn't get into water sources.

Any novel and especially science fiction involves a certain amount of suspension of disbelief, but now I just can't take the Hunger Games seriously, anymore...  It just makes it all pure fantasy.

Also, now that I think of it, they make a thing of how some of the "tributes" (gladiatorial contestants) are as old as 18 and the novels make clear that some have already hit puberty -- they "reap" (select) the contestants from the age range of 12-18 -- so you'd think that you'd also get into rape-issues in the arena, too, where an older boy/man would violate a captive prior to dispatching them.

That whole series is just not realistic...  These realizations, especially the shitting one, have kind of made it dead to me.
