I think most Sci Fi works better in B&W. Even Star Wars (try it, you’ll see). (Maybe I’m biased because I grew up with b&w televisions; I even bought one when I moved to England, much to the amusement of the counter guy at Argos, who thought they didn’t sell them anymore.)
On the whole, the 1950ies ambience just works better for me.
Just a few short weeks and the British will get to experience that 50s ambience all over again, except that UK farmers probably no longer grow turnips in sufficient quantity to keep the population fed.
