The only thing I can think of to explain the cameras is “who cares!” It’s a movie meant for kids, if it was meant for adults half the stuff in the movie wouldn’t even happen!
And it being for kids isn’t a bad thing!
If you overlook Beru and Owen’s charred skeletons, Han being in trouble for dumping a shipment of drugs he was smuggling, and Chewie not wearing any pants, sure! 😛
