Detroit Free Press:
Far be it from me to endorse yet another franchise, but thanks to del Toro and a smart script, Hellboy is so entertaining that you long to see what further heck this gang can raise.
Despite its shallow feel, Hellboy still succeeds as a piece of relentless pop entertainment.
While the character of Hellboy is entertaining, the film in which he appears is largely an exploitative jumble.
Faithful to its pulp roots and lacking the cumbersome self-seriousness of many a comic-book adaptation, Hellboy is, well, hellacious good fun.
The movie feels at odds with itself, embracing the comics' idiosyncratic creations without an idiosyncratic worldview.
J. R. Jones,
Played by Ron Perlman, he's the most magnetic action hero I've come across in a long while, though I couldn't make heads or tails of this story.
[del Toro] doesn't quite knock it out of the park like X2 or Spider-Man, but that's not because of a weak swing.
Ebert & Roeper:
... I loved about 49 percent of this movie but I hated 51 percent of it so I'm going to give this film thumbs down.
Guillermo del Toro's above-average if not-quite-spectacular adaptation of Hellboy sticks to this expectation-flipping recipe and retains the comic's cheeky, po-mo spirit.
Comic fans should enjoy the movie, but those with only a passing interest won't be as enthralled.
Del Toro clearly knows exactly what he's doing. With the big budget of Hellboy, he was given the tools to do it well, along with the freedom to do it right.
I enjoyed myself for most of Hellboy, yet the movie, a highly derivative compendium of geek dreams, is little more than a well-executed contraption.
Globe and Mail:
Making no apologies for the source material, director Guillermo del Toro lets his picture gorge on power bars of pop energy, sugared with sprinkles of playful humour.
Dallas Morning News:
Comic book-based superhero movies are a dime a dozen these days, but few are quite like the quirky Hellboy, full of dry wit and humanizing touches that balance the requisite slam-bang action.
One of the sturdier superhero movies of the last couple of years, with monsters and effects and diabolical baddies to spare, a heart as big as a house and a love story that actually gets its hooks in you.
A fully formed, funny, smart and briskly entertaining horror show.
When the movie's story line concentrates on the character of Hellboy and his relationships with those important to him, the film becomes a unique romp, with an exciting yet vulnerable superhero at the center who just happens to be the spawn of Satan.
New York Daily News:
I don't know if Hellboy has had a Beauty and the Beast relationship in his comic-book life, but if he did, the filmmakers did right by him in casting Ron Perlman.
New York Times:
Guillermo del Toro lets loose with a vaudevillian rambunctiousness that makes his adaptation of the Hellboy comic book series daffy, loose and lovable.
Despite several drawbacks, Hellboy nevertheless succeeds in entertaining.
Hellboy is one of those rare movies that's not only based on a comic book, but also feels like a comic book. It's vibrating with energy, and you can sense the zeal and joy in its making.
Hellboy is on fire with scares and laughs and del Toro's visionary dazzle.
This is the kind of movie you watch for its aura, for its appealing characters, for its marvelously sustained seriocomic romantic mood.
San Francisco Chronicle:
If you don't normally go to films where the lead characters look like giant Pez dispensers, the slogging fights of Hellboy may seem like purgatory. But there's enough going on in between the big action sequences to save the movie from mediocrity.
It might be hell on earth, but in del Toro's hands it's schlock heaven.
Unfortunately, after setting up this fresh blue-collar scenario in the movie's first hour, Del Toro wallows in pyrotechnics.
Del Toro, in love with his source but never overawed by it, keeps things moving; Perlman ties it together with some of the driest witticisms this side of Indiana Jones. Like we said: fun.
A fiery action picture destined to please fans of other comics-turned-adventure flicks such as X-Men. The rest of us will find ourselves left out in the cold.
You don't have to be a geek to appreciate the hard work and inspired choices of craftspeople who brought Hellboy into a new dimension, from page to screen.
To his credit, del Toro does not flinch from the ridiculous. But he is equally sensitive to Hellboy's pulp poetry.
