To address most concerns regarding the appropriateness of the show: It's extremely mild. While there are combat scenes, it's mostly done behind the wheel, using advanced car-weapon systems, and as expected of a kids show, the main villains always come back.
The "Mild Trash Talking" is comparable to 1st grade Recess, the "violence" is PG at worst, and there is little Consumerism pushed on the audience (Your child may want a new Hot Wheels toy car. They're what, a couple of dollars? Parents are lucky it's not some new Star Wars, with kids asking for lifesized R2D2's and a closet full of Lucasarts Halloween Costumes.)
This show deserves Awards for it's Reproduction Value, network recognition for it's ambitious storyline, and a chance to earn your viewership for the positive values BF5 instills.
