On the strength of Ness’ writing, the central conceit of the episode is able to transcend its apparent artifice, instead providing the impetus for some powerful character drama. It’s often moving, consistently nuanced, and regularly insightful; Ness has a real ability to get to the heart of his characters, and Detained is the best example of this. There’s a real energy to this episode – it’s a tense, moody piece of drama, quite unlike anything the show has given us so far. And yet, in many ways, one can’t help but feel that Class would have been significantly diminished, to the point of being incomplete, without this episode.
Frankly, this is undoubtedly the best episode of Class’ run. If we get a second season, more of this, please.
