Continuity mistake: At the fair when Isabelle goes to give Suzanna the baby, she actually hands it to her in one shot, but in the next (a split second) Suzanne shows no sign as if the baby ever left Isabelle's hand. (01:38:24)
Other mistake: The kids dare each other in a decrepit water tower which is mysterious in a number of ways: 1) Draining the water causes a powerful vortex, but the water level is not going down. 2) No one seems to work the bottom valve, but the vortex comes and goes. 3) It is absolutely impossible that anyone could swim through such a vortex, but Stu does. 4) The rotten roof breaks under the weight of little Billy (the ice-cream excess?) but carries his brother who weighs about 4 times as much.

Factual error: Bones calls the Drill Sergeant "Ma'am" or "Sir" several times and she never does anything. Anyone who has been through Army Basic Training can tell you, a Drill Sergeant will NEVER let "Sir" or "Ma'am" pass without comment. And this is not a character mistake, It would be like calling a Senator "Governor" or a Catholic preacher "Rabbi" and having them ignore it.
