While not the weakest of The Office's four seasons (that dubious distinction goes to Season 1, before the show escaped from its British inspiration's long shadow and found its own voice), this was not one of the show's better outings. The reliance upon hour-long episodes early in the season resulted in too much weak material that would have otherwise ended up on the cutting room floor being left in, while the character of Michael Scott at times came dangerously close to becoming a cartoonish characterization of a previously fully drawn character.
The worst thing about this DVD set, though, is the price that customers are being asked to pay for what was essentially only half a year's worth of episodes, due to the writer's strike interrupting production. This is barely half a season's worth of episodes that could easily fit on two discs, and I think it's unconscionable of NBC to try to make up revenue lost to the strike by releasing a 4-disc set at a full season price. On the other hand, at least the writers will get paid something for them, and the season was not without its share of cringe-inducing, yet hilarious moments, particularly towards the end, and the incredibly talented cast never gives anything less than their all.
