Hm. Well, I have to be completely honest here, this is coming from the average movie goer here. I haven't even seen the first one, I know absolutely nothing about Hellboy, and I haven't really anticipated this movie at all. In fact, the TV spots got me to see it, so there you go.
Anyway, the thing I liked most about this movie is what had me interested to see it in the first place. The visuals. Honestly one of the most visually exciting and interesting movies I've seen. The Elf (Were they elves? I honestly know nothing about this character) King turning to whatever that was (sand?) when he died was great, and I couldn't take my eyes off his Bib Fortuna type fellow trying to keep the prince out.
The old lady with the cats was one of my favorite parts of the movie and the troll's market was fantastic, so many absurdly imaginative characters, and that 'tumor,' wow. On the visuals alone I might see this again. I've looked it up and the Angle of Death? WOW.
Now, I do have a few problems with other parts of the film. Actually most of them aren't problems, just things I was rather 'meh' about.
So, on that, some of the dialog seemed a little forced.* Liz (The women with the fire, see? I told you) had some parts that were just bad in my opinion, just lines that were bland, lines that sort of take the short cut and don't have much meat to them.
Another big one was the Villain trying to talk Hellboy out of shooting the giant "plant monster." The whole sequence with him on the roof really would have been better with more build up of the Humans VS Freaks (That the right word) conflict. I know, they call him ugly and stare and the department gives him ****, but it didn't seem like it was developed enough for me. Concerning that development, the threat of the Golden Army seemed greatly underdeveloped, it just didn't seem that urgent.
In addition there were some plot wholes that I didn't really like, you know, why doesn't he just shoot the guy, why didn't she just melt the crown, doesn't he know he won't kill her because he will die too? But this actually didn't bother me that much, I expected a fun action packed film with great visuals and thats exactly what I got. It really was all over the place in tone, comedy here, serious here, etc, and while in some films that would be a negative I think that thats what the goal was here.. Making room for the bad dialog in some scenes and underdeveloped plot points, I still think the film succeeded fantastically in what it set out to do. Of course, maybe I'm off 100% and I don't know the first thing about what the goal was here, but thats what I'm thinking now. If I'm wrong, so be it.
I think that its important to look at what the film is supposed to be when reviewing it. For instance, I looked at a negative review of TDK saying it is too long and dark. Looking for another Iron Man, that perfectly accurate, but I thats not what it was meant to be.
*I think that my dislike of certain plot points and dialog being underdeveloped in this film may be because of my not having seen the first film, not understanding the characters fully, etc. So taking that into account, while I do think as I saw it the film had some problems in that area, it wasn't a deal breaker for me.
