Beetlejuice would have been as hot of a theme as GB...it’s nostalgic yet still beloved today. The character, music and art design are iconic. It would have been a far better theme to pick than Munsters...while iconic and classic, just doesn’t have the pull or relevance that Beetlejuice still does.
That being said - no one should do Beetlejuice pinball if they can’t get all assets with the license. No voices or Danny Elfman music = DOA.
