From the trailer I got a weird Asian vibe re one family, not their surroundings. No idea what the family was named, probably the Michaelsons. The family that was visited by grandparents. Even the hairstyle of the infant starting the trailer looked Asian-ish to me, although I'm pretty sure that hairdo is rather common (and practical) to infants/toddlers all over the world ;)
Is there any past immigration/cultural influence involving any Asian country in the RL area that San Sequoia is based on?
