It looks similar but the stories are quite different.
Obviously I did not want to imply that
Space: 1999 was plagiarizing
2001: A Space Odyssey. But it is quite obvious that the latter is the greatest source of inspiration for the former, from a thematic, visual and aesthetic point of view.
There are two problems with this type of approach.
The first is that, of course, the authors of
1999 are not Kubrick. Kubrick was a genius who knew how to perfectly mix the
2001's elements thus creating a masterpiece. They didn't.
The second one is that a tv show is differente from a movie. For example, a wooden dummy can go very well as a character in a movie. You can not say the same of a television series. If you want the audience to grow fond of the characters and come back to see a new episode every week, you have to try to make sure that said characters have a personality that differs somewhat from that of a cardboard.
Really, if she occasionally didn't speak or move, you might think that she is a wax dummy.
