Please tell me the name of the sci-fi movie where a mother and son are brought into a new type of society that is fascinated/disgusted by the though that she bore her son instead of growing invitro. The mother and son sang a simple lullaby/song as she was dying in a sick bay. In one scene the recently dead were displayed in clear tubes. Just flashes of memory. Do you know the movie?

Sounds a bit like Brave New World?
