Great characters, very well defined, very well acted. Nice lead-up to what the workplace actually was, with hints along the way. And the struggle of the main characters to come to terms with their situation as women and as employees of the company they work for was well-played. I also loved the cheerful music that played every time the button was pushed. It was delightfully sinister.
What I didn't like
There were many scene changes that could have been better defined. It was sometimes hard to tell where the characters were. Also, each of the characters had a different shift, yet there were a couple of scenes where they were all together at the workplace. And there was one male actor who played three or four different people. I think those characters would have been clearer if those parts were split between two actors.
My overall impression
A very interesting, edgy, Twilight-Zone-esque story that addresses a current, relevant topic in society today. Very entertaining yet thought-provoking.
