Unsatisfying ending, on multiple levels [SPOILERS]

Unsatisfying happy ending, on multiple levels.

So, the beauty/horror of the other Body Snatcher movies was the near-certainty that the Body Snatchers were going to win (OK, the 1956 version gave some hope, but the 1978 version was completely hopeless).

But this one... Not only is a cure found successful, we're told via a one-year time lapse that it's being mass-applied all over the globe. And the cure is 100% successful. And the aliens have no defense to it.

And she is cured. And her son stays alive. And her son's friend makes it. And evenDaniel Craig her boyfriend makes it. So she gets it all. And the world is saved.

They might was well just had a Disney graphic put up saying "And They Lived Happily Ever After... THE END." Uh, and please don't claim the quickie callback by Daniel Craig with the newspaper and the voiceover "darkens" the ending. If anything it cheapens it, by being so obvious and trite. And it should be obvious that a real world with real human beings (and all the problems that that entails) is preferable to a "perfect," conflict-free world populated by aliens.

I think a much more inventive ending (if it had to be "overall upbeat") was to at least leave a slight element of uncertainty/doubt as to the ultimate success in completely eradicating the infected.

It would've been much more satisfying ending if we were somehow given to know that one or two of the people we thought were cured were actually not. And that the battle vs. the aliens was going to have to enter a much more protracted and devious stage.

Once they realized they were on the defensive, outnumbered, and about to be wiped out by human countermeasures, could they not come up with their own innovations? These infected had the intelligence and memory of their hosts and some sort of alien empathy, right? Could they not use that intelligence to hone some ability to fake emotions, to blend in? They're smart enough to recognize emotions in others, after all. (Nicole Kidman's black secretary did in fact convincingly fake emotion at one point, to coax her to drink the tea.)

Additionally, could not some aliens be immune to the cure, flipping the script, so now the aliens need to preserve those 1-2 immune aliens at any cost-- and now its the humans hunting them down. At some point, the viewer might even be made to feel sympathy for the aliens (if they can forget, for a moment, that the alien is in fact a parasite).

Also: what happens when 2 aliens have children (who are presumably born infected or immediately made infected). As they grow up, they are not truly infected the same way adults are (or are they? are they still parasites on a host human body?). To uninfect them is to kill the alien and reassert the consciousness of a human who, in a certain sense, never existed in the first place. [Especially so given what the premise was in the movie: that humans, once cured, have no memory of their infected period; such a child, once cured, would have _no_ memories whatsoever-- they possibly would revert to the intelligence of a newborn.]

Or (even weirder) what happens when the first aliens-from-birth ("second generation") themselves have children? These "third generation" children are "victimless." To change them back to human truly gets complicated (both morally and as someone trying to write a movie screenplay about it).

Another variant, in an alien-dominant world: what if infected aliens cannot produce children and require uninfected humans to serve as host bodies? So, the alien population, once it becomes dominant, will nevertheless require a substantial number of healthy female hosts in order to perpetuate their race. Yet it cannot let them just run around freely lest they engineer some device or vaccine to combat the aliens. Conflict ensues. [Almost "The Walking Dead" meets "Coma".]

Another variant, in a human-dominant world: the vaccine is _not_ conveniently 100% effective, say it's only 97%. So there are still millions of infected. They are isolated and interned. But what next? If they're in "alien" prison, they are successfully neutralized from further infecting others. Should they be executed? Would the aliens attempt to escape? Wouldn't many family members (or lawyers) object, hoping for a future cure? Oh yeah, and what are the "civil rights" of an alien? ["Battlestar Galactica"-like issues pop up.]

So, not only are there better endings for this movie, THERE ARE MANY SEQUELS HERE! You don't have to keep retreading the same Body Snatchers film each time. (Hollywood producers: call me.)
