I reveal my inner Grinch to say I kind of hated on this movie, and this sentence from Ebert has stayed with me for quarter of a century:
…at one point, David settles down to wait a very long time for the Blue Fairy, and the movie intends his wait to be poignant but for me, it was a case of a looping computer program–not a cause for tears, but a case for rebooting.
I never accepted that the mechas were conscious, so the story collapsed. This was a mildly controversial take at the time amongst my local fellow SciFi fans, which puzzled me, given Ebert got it. As the developing cliché goes, humans are failing their end of the Turing Test, we are far too willing to assign agency to baked sand wafers.
