I love the Hellboy and BPRD comics, the novels, and somewhat the two Del Toro movies; the second one is much closer to the comics than the first. So this drops:
No Del Toro or Ron Perlman.
The makeup on David Harbour (drunk loser sheriff from Stranger Things) prevents him from using his face, which he can't anyway, or speaking clearly. They should hire Ron Perlman to dub in his voice, like James Earl Jones did over David Prowse. Harbour's mouth full of oatmeal sound is unacceptable.
Billy Idol's fun, but is completely inappropriate in tone for Hellboy, which is Brothers Grimm seen through a Lovecraftian lens. Maybe go Celtic and have Faith & the Muse, or Nightwish. This is bullshit.
I've seen a couple of Neil Marshall's movies: The Descent and Dog Soldiers. Both are good B-grade horror, on cheaper than nothing budgets, mostly single shaky-cam following about 4 amateur actors through a dark wilderness; his other two movies are more of the same, though I haven't seen them. I have zero confidence that he can run a big-budget thing with characters and try to get acting from them.
Lots of big action scenes, which rather misses the point of Hellboy; there's usually one or two fights in an entire Hellboy comic story, mostly quiet investigation and character interaction.
Yeah, no. Waiting for streaming on this steamer.
