The episodes are good, but some of the physical cues are obviously forced by the actors in question (they also rely _a lot_ on the audience not missing any episodes for fear that they won't get why the camera is focused on a shoulder or lips at a given point). What really dropped the quality for me, though, is the uselessness of the "bonus features". Not only are they only on the final disk and, with no easy way to reference the names of episodes outside of checking the inside covers, force you to try to remember through the whole season to which episode the "deleted scenes" are from, but they are also almost completely simply alternate shots for material already included in the episodes. Nothing in the deleted scenes accents or adds to the show in any way.
The one bonus feature also fails to hit the mark as the only clips they show are from the episodes. Even just having some clips from casting calls would have allowed this set to at least be worth a four-star rating.
And, finally, there are commercials at the start of the final disk as well as a completely unrelated preview included in the "bonus features" of the final disk.
