Too many unrealistic and overlooked flaws in many aspects. Couple things I noticed was they were barricade doors with easily movable objects like table with wheels, wooden spool, and an aluminum filing cabinet. Another thing I noticed is they would shoot at the ground a lot and they sometimes fire 50+ rounds before reloading their weapon. But the worst has to be an episode 8 when son firing an Uzi is holding the gun by the tip of the barrel. They need way better weapons training and the editing crew needs to catch these unrealistic instances. Because personally for me this show has huge potential but every time you start putting yourself in the show so to speak these flaws snappy right back out.
