I think the comparison to Addams Family is apt. A fumbling of tone with a subpar score. I think there’s a healthy dose of Wonderland here too, especially during the act two opener when the entire ensemble dances around in Beetlejuice costumes, much like the multiple Alice’s when Alice first entered Wonderland.
I also couldn’t help but think of Rocky (though the tones couldn’t be further apart!). Maybe it was the same director in the same theater, but as Hamilfan states, they kind of wanted to have their cake and eat it too re: altering the characters and plot, but still throwing in many of the classic movie moments like Day-O. Rocky had to include drinking the eggs, climbing the steps, Eye of the Tiger, etc and no matter how much Beetlejuice changed the characters and set-up, they couldn’t escape including all the equivalent film moments here too.
Marie: Don't be in such a hurry about that pretty little chippy in Frisco.
Tony: Eh, she's a no chip!
