At this point, the Hellboy franchise has moved on and Guillermo del Toro isn’t part of it anymore.
Del Toro made it clear before the reboot was announced how much he wanted to make a Hellboy III.
We can pretty much guess that the director isn’t thrilled that the reboot is happening as it basically kills any chance that was possibly left for a third film, but asking del Toro just how frustrated he is doesn’t accomplish anything.
While that is obviously frustrating for those of us that loved the two movies del Toro made, it has happened and there’s nothing anybody can do about it.
