Pity that Spencer didn't know what his grandfather was told about Bravestone - that Jurgen killed his parents. It would have been "dramatic" in their final encounter for Spencer, as Bravestone, to say something like "Do you remember me? You killed my parents when I was a kid. Now it is payback time!".
Sure, maybe it is a cliché , but IMO it is suitable for an adventure/comedy film. What do you think?
