Yep, I went to go see Jurassic world. I really enjoyed the movie because I love the Jurassic series but there were some things I didn't understand.
from what I deducted Jurassic world takes place 23 years after Jurassic park and they are still using small caliber rifles and shotguns to take down dinosaurs, you'd think after the incident at the first park they'd have a better armory with larger caliber guns that can take down an elephant. Hell, the only powerful gun they seem to have would be the M134 Minigun with explosive ordinance. Honestly, I expected them to have TOW launchers like the first movie did but nope. Owen and Barry had guns that made sense considering they are meant for hunting. I understand they aren't the military but still, you have a Tyrannosaurus Rex and the new Indominus rex and they still think a 12 gauge shotgun and taser rifles will really stop them?
Another thing, you'd think they would have Emergency buildings so if something like the incident at the first park happened again there would be safe rooms that the dinosaurs couldn't get into so civilians have someplace to go
And how did Zach and Gray fix that old jeep? Gasoline doesn't last 23 years and even if they could find another battery it wouldn't have a enough charge to start the car or even if the car would start because this jeep hasn't been moved or used since 1992*
