If you like these actresses, it's fun to hang out with them for 70 minutes (plus a few more with the bonus featurette). If you don't know them, but you're curious about the genre, this will have a few interesting tidbits for you. For seasoned veterans, there's probably not much in here you haven't already heard in several other documentaries or audio commentary tracks.
It's a little interesting as a historical artifact, to see who was paneling a typical horror con back in '04, and the sorts of conversations they had with each other after going back to their hotel rooms. Beyond that, not much going on.
If you do want to see this, the only way seems to be directly tweeting Happy Cloud Pictures, as they're selling DV-R's of it but not on their website.
P.S. To the people who directed Lilith Stabs in those unreleased films she mentioned, RELEASE THE FOOTAGE TO THE PUBLIC.
