>>106959372The obvious thing is that 95% of your audience will only vaguely remember Hellboy as a character, meaning they remember "Sarcastic red demon guy with a big gauntlet" and little else, if they remember it at all, so you're already alienating a certain percentage of the audience who won't want to see the third part of a story they don't remember, especially since there's a built in expectation that movies come as cohesive trilogies that are meant to tell a larger narrative and not just semi-independent adventures with the same character
You could make a Hellboy movie that doesn't just retread his origins, which this one sort of does, you just can't call it Hellboy 3. Also the movie shouldn't be a terrible rip-off of Deadpool
