It feels bigger than the original show — and smaller, too. Here, as in any of the program's 120-odd episodes, we watch a grade-Z movie — in this case, the 1954 utopian sci-fi potboiler This Island Earth — unspools in its entirety. In the corner of the screen sits our defense against the trash: three silhouetted figures, a space prisoner (Michael J. Nelson) and his robot pals, who supply an exuberantly sarcastic running commentary on the awfulness of what we're seeing. MST3K: The Movie has more than its share of gonzo laughs. It turns out, though, that when you take the show out of the living room, transforming it into cinema, the sophomoric devilry seems less casual in its glee. B+
