The younger daughter gets married, even though Andrew is her best friend. More time passes. Andrew wants his freedom. He builds his own house on the beach. More time passes.
People get old and die.
First he has fake skin plastered all over his body, then fake nerves inserted, then fake organs, and so on. This is billed as a family comedy, but it will never succeed as one. After that, it eventually becomes even a little dark, as Andrew struggles with the fact that's immortal, but all the people he loves aren't. Such a great space of time should give us the feeling we've watched a sweeping epic, a grand portrait of one robot's journey through life. But it doesn't.
