(spoilers in reviews)
At Comicon
Nick from Chud reviews it at CNN
Also, Chud has an interview with Ron Pearlman and another with Selma Blair.
If you like your interviews to feature pop-ups of girls in bikinis, there is also another interview with Ron Pearlman at FHM where he dresses up as Hellboy to shoot pool with the interviewer.
I’m going to see it on Friday 
Here’s an intro to Hellboy, with many scanned pages of comic art.
I hope that my reaction to it is closer to Nick’s “this restored my faith in movies” response as opposed to the more critical “movie is pretty but has no plot” take on the film from some of the comic book sites.
