In a bit of utterly shameless self-promotion, might I suggest as stocking stuffers three documentaries starring ... myself. "Fahrenhype 9/11" is a really professional demolition of Michael Moore's "Fahrenheit 9/11."
"Michael Moore Hates America" also takes on Moore, but uses humor as its tool. I found it quite amusing. The plot is their attempts to interview Moore (who goes to great lengths to hide from any possibly hostile interviews, down to refusing to give out where his studio is actually located, and using a mail depot as its address). I particularly liked the scene where they talk to the mail depot, discover that the depot will notify Moore's shop immediately if anything perishable is delivered ... so they go out and get a big bunch of roses, deliver that with a sweetheart card addressed to Moore and asking if he'll give them an interview now.
Finally, radio and TV host Larry Elder's "Michael and Me" started out as a rebuttal to Moore, but evolved into a broader pro-gun documentary. He must have invested a fortune in it, as it was shot on film rather than video (which increases materials and editing costs by a factor of ten or so).
