Saw it last night - I'm a huge fan of the original film. Got my Sideshow Collectibles BeetleJuice pre-ordered, a couple prop replicas, and steelbook to prove it.
As excited as I am - I just keep thinking that "Hm. It was fine." Which it was. Catherine O'Hara stole the show, for me. She's effortlessly awesome. Keaton was near perfect - the only issue I had is that BeetleJuice felt like his edges were sanded off a little more than I'd hoped.
There also was a lot more 'fun' spirit in this film than the cynical, myopic vibe of the original. And less hints of genuine darkness. Remember the wedding clothes seance? That scene was genuinely creepy - musically and visually and vibes-wise. I missed some of that energy.
Elfman was more subdued and needle-drops were much more the focal point, which I wasn't a fan of.
Plot-wise, the ex-wife was completely not needed, and the film seems to think so, too. Like literally...take her out, and the film is the exact same. We see her wander around a few times, soul-suck, and she shows up at the wedding to be disposed of immediately.
We also could've not used Jeffrey Jones' face, literally. He gets paid because of that which negates his lack of involvement.
Anyway, I may see it again. But it was fine. 5 or 6/10.
