I think Buck Rogers is an absolute riot of disco sci-fi. I've watched some recently and it seems obvious to me they were very self-aware of it as well. Unfortunately, modern viewers can't tolerate even a whiff of cheese in their entertainment.
I like shows with dated visuals, it's like you get a double dose, you get the future but you get it as imagined from a (now) retro time. I think beehive hairdos, sideburns and mini-skirts make TOS better not worse with time.
