Asimov's story has not received many adaptations, and as such this is a welcome flash. However, I personally thought the addition of humor to the story didn't work very well, both because I didn't find it particularly funny, and because it's a serious story. I also found some of the designs, particularly that of the robot itself to be a bit to cartoonish for the serious subject matter. Finally, the voices needed work, both acting wise, and in the case of Dr. Calvin, quality wise (though the subtitles solved most of the latter problem).
Despite its problems, I'd love to see more adaptations, and I'm sure you can improve. Nice job. (3/5, 7/10)
