Supposedly a reboot of the film series started by Guillermo del Toro, based on the Hellboy Comic Books. I was expecting far worse. As it is, the plot is disjointed. Characters feature for no obvious plot purpose beyond showing off CGI and none of them have any particular depth. I suspect the Hellboy character would have even less depth if I hadn't seen the the two previous films, but David Harbour does a fair impersonation of Ron Perlman (and the make-up/prosthetics are nearly the same) so for me a lot of that was carried forward.
So, yeah, the story kind of made sense and it trundled along without much threat or menace. The new character "Alice" was interesting but ridiculously underused. There was a standard soldier-secretly-a werewolf/tigerish thing that was ridiculous as it didn't do or achieve much. The acting was generally OK throughout. Just, why did they bother? It's so like a knock-off worse-version that they would have been far better advised to make the 3rd in the existing series.
