First, I'm not in the habit of panning films. My worst criticism has always been "It's worth seeing, but I wouldn't buy it." This remake of the Stepford Wives has set a new standard. Don't even rent it.
I do not know what happened - whether they ran out of money for SFX or the stars demanded more of the budget than they'd counted on, but whatever it was, it cost the movie.
Basically, there are 2 ways to view this story Scary or Funny. They failed at both. The book and original movie were spooky and disturbing. Frank Oz set out to make the remake a comedy, but failed. There is no continuity or consistency. Are the Wives Robots, or brainwashed women? Either could be true. One of the deleted scenes shows Bette Midler turn into Inspector Gadget (interesting, since Mathew Broderick is in the film, too) sprouting a variety of kitchen utensils from her fingers, and finally dropping a lawn mower from her butt, which she then rides out into the yard to cut the grass. It was both disturbing and funny, and there was no doubt that she was a robot. So they cut the scene. I think they suddenly realized halfway through the production that they wanted a happy ending, and that wasn't possible if the human wives had been killed and replaced with automatons. So they cut the scenes where their mechanical nature showed, but not all of them - there's still enough enough glimpses of Faith Hill giving off sparks, and serving as an ATM machine. The possibilities of the robots had great comic potential, which was abandoned. Another cut scene had the husbands urging Mathew Broderick to get the cigarette lighter option - "You'll be glad you did..."
Bottom Line: The Remake of "The Stepford Wives" isn't funny, and it isn't scary, it's just sad.
