What's the general run time of the doll sequences in relation to the full film? Looks like a human interest tale given the subject matter.
I did watch the documentary and the guy Hogancamp has an almost infantile way of processing his thoughts and motives.
On a side note, I used to collect action figures as a hobby, and at a certain point I had to choose between that or video games and movies.
That being said, what Mr. Hogancamp has invested in his doll and vehicle collection would have killed me several times over. But the one thing I'll eternally tip my hat to him is how he crafted his playsets. Those were some kick ass playsets he did! When I was into Star Wars collecting, it pissed me off to no end that Hasbro couldn't make one decent backdrop.
Now, when you go to conventions, you see these sprawling dioramas, and no thanks to the toy companies.
