"Wicked Little" movie review

Wicked Little: A family moves into a cursed property and has to battle it out with kid zombies. This story might be more scary if I were a Jew that kept Kosher, as the only original scene was a group of zombie preteens slaughtered and ate a raw pig. (I guess the "raw" part is pretty obvious, as zombies aren't into the whole cooking thing.) The movie came off as a cross between "Friday The 13th Part II" (without the T and A) and "Lord of the Flies." The story arc was extremely close to that of John Carpenter's "The Fog."
Typically, I would watch this movie in fast forward and save and hour and a half on my life, but I had time to kill.

There are some entertaining scenes of the kiddy zombie crew walking through the black forest after a tough day of killing and eating the local teens with pickaxes in hand like a demented version of the seven dwarfs. It was fun to break into "Whistle While You Work" as they returned find a horrified Snow White.

Questions: How did the zombies know to pop the tires on a car in a coordinated attack? The kids were killed in a mining accident a century ago in the remote wilderness where few if any would have an idea what a car was, never mind how to effectively disable one.

Notes: This would be considered a zombie film by zombie film snobs who think "28 Days Later" is an infection or outbreak film. Zombie films involved the dead rising, not an infection spreading among the living.
