As far as the film-as-artistic-product thing goes, my main complaints were these:
1) Oh my God, the ending. Liza thought the movie should have ended when David pushed himself off the ledge of the skyscraper. I thought it should have ended with David trapped in the amphibicopter praying to the Blue Fairy. Under NO circumstances do I think any sane person would have advised Spielberg to add another 30 minutes of screen time, especially with a story line as implausible as that one was. If Spielberg is under the impression that by inflicting that story line on us he was providing us with a happy ending, then he is much, much sicker than I ever knew he was. As far as I'm concerned, the "resurrected" Monica is far creepier than anything Cybertronics ever came up with. If all he wants is something that talks like Monica, walks like Monica, and has been leached of any aspects of Monica that may not have been entirely conducive to making him the epicenter of her life and purpose of her existence, why didn't they just build him a robot Monica and tell him it was her?
2) David winning the hearts of the mob at the flesh fair. I'm sorry, no. A mob whipped up into that state of frenzy wouldn't have cared even if they were convinced David was a real human.
3) Almost all of the dialogue written for the human characters. More time has clearly been spent on the androids, who are much more interesting.
4) The voiceovers. Holy Chris Carter flashbacks, Batman!
5) The opening scene in which Dr. Hobby and the Cybertronics team lays out the Big Moral Issue for us. If that dialogue were any balder it would have to pay Yul Brynner royalties.
6) Enough with the fucking Pinocchio thing already!
As far as the nastiness and foulness of the film, it basically comes down to the view of human nature, human relationships, and parenting that clearly informs it. Here are just a few of the things that made us very angry:
The fact that David is designed only to imprint on one person bears this out. Cybertronics assumes that the important thing is to bond the android to its "mother"; its relationship to its father is unimportant. Henry doesn't seem to expect David to imprint on him and doesn't seem particularly interested in him. David has an overwhelming desire for his mommy but couldn't care less about whether he has a daddy. The film is no more interested in Henry than David is; Henry is a complete nonentity whose only function is to bring David into the house and then force him out. And what *is* Henry thinking, anyhow, to bring this kid home without either telling or asking Monica first?
The result is that everything that happens to David becomes Monica's responsibility. She's the one who imprints him, she's the one who abandons him, she's the one who won't love him enough until he's real, she's the one whose absence causes him millennia of grief. Meanwhile Henry, the asshole who created this situation in the first place, is allowed to fade into the background.
Meanwhile, Monica's love for David is based on what? As far as we can tell, the fact that he loves her so unconditionally and abjectly. This is depressing. What's more depressing is that Cybertronics' whole marketing scheme for these androids assumes that this is what parents really want from children. I'm willing to believe a lot of bad things about humans, but I don't believe this *particular* bad thing. I think a kid who's always 11 would be terribly unsatisfying even to the most horrible of parents, even if they could get over his being mechanical. You can't feed these things; you can't change their diapers; you can't bathe them; you can't teach them how to talk; you can't watch them take their first steps; you can't even watch them get older. In short, there is no way to nurture them, aside from letting them bask in your maternal presence. And this is a huge design flaw, because what these prospective clients would want is to be able to replicate the experience of raising a child. Even Hasbro figured out that to make Baby Alive really sell she had to be able to eat and poop.
And so on. I know that the film is supposed to be "a cautionary tale," but that doesn't cut much ice with me at this point. We've been told this exact cautionary tale so many times that I can't really see this film as making a unique contribution. Oh, you mean that creating an autonomous sentient being who's smarter, stronger, and longer-lived than us, but so different from humans that he couldn't help but be alienated from society, would be a bad idea? Hmm. I think I remember reading some really old book by some chick named Mary Shelley that said something about that...or no, wait, maybe I'm thinking of Rocky Horror Picture Show. What would be a challenge would be figuring out how to tell this story so that it doesn't end in tragedy. That'd be a movie. This is just a waste of eight bucks.
