It hit me when she went off road and lied to them that their on a different mission and her soldiers just rolled with it that she's taking them for a ride and ultimately going to make them road kill. Her soldiers only realizing she made a wrong turn after seeing their own brothers attacking them. (puns intended)
Some real heavy shit happens like the very pregnant one getting killed, as well as her baby. Learning to trust some men and that they're not all bad (Max and Nux), after a life of abuse by men. Tons of heavy stuff, but nothing really heavy enough to contemplate existence or change the way most people live their daily lives. It was fun and a great time but not really ground breaking as far as the plot goes. But then again maybe I've seen to many movie/read too many books that I feel that way.
