The Doom That Came to Gotham is almost a companion piece to Gotham by Gaslight (2018). Here we have a turn-of-the-century Dark Knight investigating a cult who may be trying to summon up ancient forces of evil (spoiler: they are). Forbidden books, vast tentacled monstrosities and madness abound.
Lots of the usual Bat cast are thrown in - some given horrific make-overs, some don't make it to the final credits - and the voice work and animation are all above average. David Giuntuli is a terrifically fierce but impassioned, human Batman - he might be one of the best of the many voice actors in the role. This is a truly dark night for the Dark Knight, who at one point just stands in the Batcave and announces Gotham is doomed over and over again. To the wall.
As much as the movie uses such classic tropes and conventions from HP Lovecraft's stories, the biggest one - the overwhelming sense of unknowable dread - is something that just can't be conjured in a 90 minute animated action adventure. Slow-building tension and increasing unease are something it just doesn't have time for - also the problem with the first Hellboy movie, which Doom That Came to Gotham is very similar to.
However, as an atmospheric period superhero adventure, tinged with nightmarish horror, this is a winner.
