"Why won't you believe me...?"
I know: the premise is pretty much a cliche- the central protagonist, straitjacketed, in a padded cell and surrounded by disbelieving psychiatristswho think said psychiatrist is mad. It seems almost a tradition that every television serial has to feature an episode like that, always commencing in media res, with the protagonist already in said cell.
Yet it works particularly well here. Partly it'ds doewn to the meticulous plotting. Partly it's because of the fact that the Batman backstory alreadsy featyures Arkham Asylum, which gets a little more depth here, and partly because, at long last, we finally get a bloody good Scarecrow story, one in which the villain comes across well, and in which his nightmarish visage has a genuinely chilling effect, given the cleverly evoked sense of unreality that pervades throughout.
Still, that's quite a few Scarecrow episodes now. Batman hallucinates his rogues gallery, although several of them, not least Penguin, haven't really appeared much as of this point. This aside, though, we have a pretty much flawless episode.
