Documentary update

I did this a couple months ago, but I wanted to update the list.

Good premise with poor execution:
Wal-Mart: The High Cost of Low Price
Devil's Playground
Unknown White Male
F For Fake
Dark Days

Fairly good, although the film's subject wasn't very interesting to me personally:
Manufacturing Consent
Hearts and Minds

Effective, touching, and intelligent:
The Corporation
Spellbound
Tying the Knot
Various episodes of 30 Days
Mad Hot Ballroom
Paperclips
Sketches of Frank Gehry

Entertaining, hilarious, and engaging:
Slasher
Supersize Me
Wordplay

Apparently unmemorable, because I can't remember my opinion of it:
The Saint of 9/11
