Kind of Silly
I don't really get why the capital rigged their own city to blow up and booby trapped it with the stupidest defenses possible. Really none of their actions make any sense in this movie.
In the first two they have elaborate impractical death traps, but it sort of makes sense given that they are being televised for entertainment. But how the heck is that practical in a war? An outdoor flamethrower that eats fuel? (At least in a sealed room it'd eat oxygen while charring.) Motion-sensor triggered guns that fire all of their ammo in random directions instead of using that same motion sensor to, I dunno, aim and track the target? Weird goo stuff that fills an arena where all the doors seal except one that conveniently leads to a building JUST tall enough to not be reached? Really? Is it any surprise the only actually effective devices were conventional landmines and bombs, which probably took about 1/100 of the time and resources to actually set up?
It also doesn't make sense why they bombed a building that showed up on camera 5 minutes earlier and declared her dead as if they never considered that she could have left. Seriously, the girl's supposedly died like 5x by now, maybe take the extra 2 minutes to actually make sure she's dead? Also, the "omg is the main character dead?" trope works way better when confined to like once per movie, tops, not every 20-30 minutes.
