It's a very ridiculous series. The premise is that the apocalypse is coming, the Four Horsemen are on their way, and for some reason this is causing a series of mysterious events in a small American town, which must be investigated by a rookie cop (short, female, black, wisecracking, named Abbie) and Ichabod Crane (tall, white, sarcastic), who in this telling is an English turncoat/spy from the US Revolution who has slept for 230 years, but has none the less awoken full of investigatory zeal, pausing not even to change his pants before flinging himself back into the action.
Most of the details make no sense, but there's more than enough good lines, pretty faces and panache to cover these up as long as you don't look too hard at the joins or the history and hum loudly when scepticism threatens to break the illusion.
At the moment I am very pleased that Ichabod Crane has been confirmed as being somehow an Oxford History faculty member at Merton, despite being 230ish years out of time. I mean, OK probably Merton would notice, *really* if they got a call about one of their dons from a previous century who had never officially been removed from the list - but wouldn't it be great if they didn't? Although I vaguely have the impression that Merton might be too efficient and not mysterious enough for that sort of thing. All Souls might be a better fit.
*if you don't find watching long video content online painful, this may be because you don't live in a small Cornish village connected to the outside world by a shonky strand of copper installed around 1938.
