I have Opinions about the ending(s) ((who doesn't))
I don't like Seymour getting a happy ending he didn't earn, the released movie ending is cheap and feels rushed, and makes us miss one of the best songs in the show. Seymour killed at least two people and sold his soul to the devil, and the movie leaves us with the message that that's cool and sexy and you should definitely Feed The Plants
It's also such a bummer that they made and filmed a huge climactic scene and didn't get to use any of it and I can't imagine how it felt to have to just, cut it.
So, problem: There's no curtain call in movies, so the deaths of the main characters felt too final and dark for test audiences.
Solution: Bloopers during the credits!!
Problem: Audrey and the World shouldn't have to pay for Seymour's mistakes
Solution: Make Seymour sacrifice himself to defeat Audrey II! Seymour pays for his faustean bargain, including paying the ultimate price to allow the person he loves to find success!
Problem with the solution: Neither Audrey nor The World are blameless! Do they deserve to die for their faults? Mmmmmmnot quite. Maybe. Certainly Audrey dying for her crime of never taking initiative, for allowing herself to be pulled along by whomever is not a just punishment, so much as a thematically appropriate one. But losing Seymour, being forced into having to stand on her own feet and take care of herself -- both her Devil and Angel being taken away from her -- that would work, too. Twist Somewhere That's Green to be referring to Seymour getting eaten (or, uh, crushed, maybe) and that's a winner.
The world, though. See, the thing is that Seymour didn't do any of this on his own. The invasion of Mean Green Mothers is a result of humanity's -- collectively -- greed. The World pushed Seymour into a cycle of more and more and bigger and bigger -- The World bought Audrey II's en masse -- The World fed those Audrey II's. Of the issues in the ending, this is an easy one to miss -- but the invasion isn't a result of one Mean Green Mother. It's the result of hundreds or thousands of people all making the same bargain that Seymour did. Don't Feed The Plants is a judgement not of Seymour, a punishment not of Seymour's mistakes, it's a judgement of humanity as a whole.
Anyway. Love the movie, so so much, and since the original ending is available I don't super mind the released ending being the one attached to the film. I can go pull it up on youtube or whatever and watch the ending I like and the people for whom that's too dark can get their happy ending. Everyone gets what they want
