***SPOILERS AHEAD***
I saw it on TV from around half way til the end, I didn't like it.
The basic idea was good, the boy trying to imitate what is human, with confusing results, showing how difficult it in fact is to define life. I got interested in the plot. But oh no, here comes Steven Spielberg with his sugary daydreams; the ending was horrible. Why did they try to "explain" trivial things in alienating terms? What happened to the problem of identity? What's up with these traditional, mundane looking alien figures, and why did they have to force them into the story? Did the writers think they were "flying high" when coming up with the pseudo-scientific, philosophical ending conclusion? Why did they ruin the fantasy world they had created, by denying us what makes all art worth experiencing; The freedom of interpretation, - and instead use half an hour (or more) of the ending for senseless, numbing dialog (or rather a monolog)? There was potential for something much, much better.
