I'm a big Christopher Guest fan and honestly went into this film expecting to be disappointed, but wound up being pleasantly surprised. Chalk was very entertaining, often hilarious, at times touching, and even managed to pull everything together to actually tell a story pretty well. The development of the Mr. Lowery character from start to finish was great. There were only a handful of actors in the film (the rest were real students, principals, teachers, etc.) and they were great. Troy Schremmer was excellent. Anyhow, I highly recommend this to anyone who enjoys finding comedy in the ridiculousness of life or basically anyone who enjoys good mockumentaries. Or, people who are teachers or are related to teachers and know that world. Two thumbs up.
