>>107781482The cartoon is pretty obviously a separate canon.
Movie Beetlejuice is just an undead scumbag. That was the point; he got let loose thanks to two recently dead people and later Lydia when her parents were fucking around with exorcism shit they damn well shouldn't and the conflict became about getting him back in the box so to speak.
Cartoon Beetlejuice is basically portrayed how someone like Lydia would concoct an imaginary friend, only he's actually *real*. Regardless of shit the writers/artists snuck in as far as what we see in the show, he's just a BFF. He'd do anything for her, and certainly isn't about to try rape-marriage on her or any shit like that.
