If you read the critics’ rough assessment of ABC’s "Grey’s Anatomy" last season, you might’ve been led to assume this drama about a medical intern (Ellen Pompeo) and her fellow interns and doctors was a special kind of mediocre. But while it’s true "Anatomy" wasn’t capable of making the same kind of splash "Lost" and "Desperate Housewives" made when they premiered, and while it’s also true the show didn’t really hit its stride until season two, there really is a lot to like right from the start. "Anatomy" calls it right down the middle – neither excessively heavy like "ER" nor crazily irreverent like "Scrubs," yet able to reach either height when events necessitate. Good writing and a loaded ensemble cast (Sandra Oh, Katherine Heigl, Justin Chambers, T.R. Knight, Isaiah Washington, Patrick Dempsey, Chandra Wilson) round out a show that’s belatedly getting the praise it always deserved. Includes nine episodes (two commentaries on the first episode), plus deleted scenes, behind-the-scenes feature, foreign-film-style trailer (worth a look). Grade: A-
