For someone who hasn't read any but really enjoyed the movie, (and looking forward to the second) what Hellboy comic do you suggest buying or is the best in your opinion. I want to get into reading Hellboy but I don't know what the best issue is.
Check out the trades. Of course you should start with Seeds of Destruction. The second one is my personal favorite, Wake the Devil and picks up where the first left off. The next two trades are filled with shorter but still sweet stories and the big finale comes in volume 5 Conqueror Worm.
There is newer Hellboy material which is still good but what sets the first 5 volumes apart is the art by Mignola. Its amazing and really adds to the atmosphere of the book.
So start with the first trade and continue on from there if you like it. The comics are scads better than the movie.
