It’s hard to even pin down how it would be as an adaptation because as a film it’s so poorly made. The pacing is awful, the characters are rarely if ever given anything to do other than exposit, and the CG ranges from “oh...” to “I guess they couldn’t afford union work.”

That said, all the character changes make little to no sense. Bruttenholm becomes a callous, rude manipulator. Hellboy is essentially a manchild. Alice is Johann now, maybe? Or something? The Baba Yaga was okay until she started flailing around with kukri (?) knives. And poor, poor Daimio, being turned from a tragic monster suffering from his affliction into a third-act fist-pump action heavy.
