It's worth a rent. The art is not as bad as people here have been making it out to be. (If you want to see truly bad animation, watch Hunchback of Notre Dame 2). It wasn't, you know, Shinichirô Watanabe or Hayao Miyazaki but it had a more adult look then American made kids cartoons. The animation was real similar to what you see on X-Men Evolution, only much darker and grittier. Oddly enough, It looks almost like they're emulating the anime Helsing in color tone.
The acting is limited by the time. Hugh Jackman is a novice at voice acting and it sort of shows. He sounds a little wooden. David Wenham is very nice and has the best lines in the cartoon. ("No real lady would be caught dead wi-- perhaps not the best choice of words...") However, Robbie Coltrane was sorely underused. His vocal characterization of Mr Hyde was so great in that opening scene of the film and in this you can barely tell its him he has so few lines.
The plot is almost better than the films, and contains a lot more history and the steam-punk like flair that made me love the film and other things like Leauge of Extrordinary Gentlemen (Not the movie though.. it was horrid). I wish they had made it a full length animated feature, because the plot definitely had room to be expanded into 90 minutes.
In all, it was very good for an American produced adult animation. Too bad Universal is connected with Nickelodian and not Turner Broadcasting's Cartoon Network, because I think a Vanhelsing Animated series would play really well in Adult Swim.
