Series start with a chilly scene! Sets up the base of the series just right, however as you go on watching the series some things feels quite over the top. Story is good but the execution doesn't seems to be as good. Three kids, particulary the girl, seems to be way too ahead of her age. In finale, she kind of single handedly deal with every obstacle that becomes unacceptable. You may laugh at few scenes as well. Ending appears forced to give possibilities for a new season.
After saying so much why I gave 7 because you can binge watch it as the story keeps you somewhat engrossed. Just ignore the over intelligence of kids and you'll find it quite good.
