It felt very disjointed with too many randomly through in characters and storylines. You've got the death of the father figure, the fracture between parent and child, the self-indulgent widow, the money hungry partner, the revenge-jilted spouse, the rejected lover pining for what he lost...amongst others that I won't mention to avoid spoiling any plots. It's like the writers couldn't think of a way to renter this world from where it had left off correctly.
What really made me dislike this film is what they did to Lydia. In the first film she was inquisitive, bright, strong-willed, and clever. This film reduced her to a frightened, easily-manipulated, ghost psychic. One would think after having spent years in a house with ghosts, she'd have a different relationship with them where she understood and could maneuver her way around the afterlife. Yet here she is, a shy mouse, frightened at the perspective of even seeing Beetlejuice while also being controlled by her beau. The rest of the characters were equally evolved into shadows of what they should have become. It's like no one even understood the characters at all. Instead, this film created characters on the former characters and stereotyped them into typical tropes such as the skeptical child, the shallow artist, the sleazy partner, the jilted partner...etc. The only character I actually liked was Bob.
While I know this hints at a third film, from the direction this one took, I pray not. I'd rather just have some brain bleach to forget this one even existed.
