Both belong to the sci-fi genre. Both the dramas portrayed how the robots/aliens can be very loyal, innocent and intelligent but are misused and mistreated by humans.

Both the dramas portray mature relationships of people on their 30s. Apart from the main couple there is considerable story line for the other couples too.
