My oldest son just turned 11 and he's becoming interested in more "grown up" movies (i.e. stuff that doesn't have talking animals in it)... thanks to Netflix, On Demand, and the like he's really gotten into stuff like the Back to the Future films, Ghostbusters, the Tremors series, etc.
So the wife and I picked up a nice little box set of Ghostbusters 1 & 2 for him and the first "Percy Jackson" film ("The Lightning Thief.")
When my brother asked him what he wanted for Christmas, my son told him "I want SHARKNADO on DVD!" ... my brother actually called me later to ask if that was okay with me. I said "Sure, that's fine. He's already seen it twice on SyFy."
