Halloween is supposed to be about the kids, right? Right?
My son is the same age as yours and he's not into it, but my 7 y/o daughter is fully involved. She painted her first styrofoam wig head skull last month. She's completely hooked.
Not the one in the picture. But he came up with a design for a 2 headed corpse tonight that he is going to build and corpse if he wants too. I've got 6 skulls that we are going corpse and put on stakes.
