I've written before on this Web site how there is a standard documentary being produced these days that shows the "community" that has grown around various niche topics. Find a bunch of nerds who like the same thing and then they talk about how awesome it is to get together with other like-minded nerds. Brickumentary does a little bit of that, but there is more of the actual story behind LEGO's history and development. In addition, interspersed are playful animations and slick production. It does begin to feel like a long infomercial for the toy, but it does a good job of keeping it fun and interesting.
