Ok horror/syfy/scary ass shit movie goo rues , I have been looking for this particular movie for yearsssssss.  I have only seen it once when I was about 10 and I’m 27 now so do the math. 

Here are a couple of scenes I can recall.
 
Scene 1: There is a family living in an old farm house.  I’m not sure of the family size anymore accept for that fact there is a dad (step or real I don’t know) mother and at least one son.  In this scene the dad pushes him into the basement and closes the door behind him.  The kid knows there is a monster in there and bangs and scream to be let out.  Just as the monster begins it’s ascend the boy is finally let out. 

Scene 2: the boy is speaking with some old dude, could be an Indian or something like that…they are talking outside of a cave around a fire and the “Indian” is telling the boy of the creature.

Scene 3: Something gets pulled under the old wooden windmill that was on the farm by the creature, I’m about 60% sure it was the pet dog.

Scene 4: the boy crafts an explosive device utilizing a remote control car (or truck) and from outside the house he drives it into the foot of the beast and blow it and his house to kingdom come.
That’s about the gist of what I remember, keep in mind I was about 10  so I tried to be as descriptive as my memory would allow.

Please help me!

thanks
