I liked it, my wife hated it.
I disliked the ending, or what became the ending. The movie has a natural ending, with him praying eternally for the pixie to grant his wish. Then it keeps going for another half an hour so Stephen can have his feel good ending.
But if you lop off that last 30 minutes, and just end it there, it's a good movie. I thought the bit where he sees a bunch of robots just like him, packaged and ready to be sold, that was a bit disturbing. Very Kubrickish.
Stanley would not have mucked up the movie with the sentimental gibberish at the end, though.
