I just found another robot movie that I have not seen, Wall·E (2008). Back in 2004 I heard a beautiful song called "My prayer - devotion" when I was still in college, and then maybe 1 year ago I saw an MV of "My prayer - devotion" with two cute robots. That MV was beautiful and touching. How did I not think that the MV was actually from a movie until today I came across it? I have accumulated several robot movies to watch and many human-robot interaction papers and books to read. Life is just too much fun that I wish I had more time without worrying the deadlines.
Below is the trailer: http://www.imdb.com/title/tt0910970/
I would like to know what makes these robots cute and attractive.
