true, true..... I think ages ago there was a tv program talking in the same way about trek....
Sure, be 'realistic' all you like.... But you need to keep your audience!! there will always be 60 Yr olds, saying "its carp, they have 'sold out' ", and teens who say its great, as they have not had 30 yrs experience of the same thing being tried badly 20 times over..... :(
Problem is, without FTL, gravity generation and whatever, plot-lines become difficult and strained, to say nothing about having to build a set with those restrictions.... and the audience loses patience...
- no chance of 'calling for help' if it takes them years to get there..
- 'no gravity' acting may be nice, but is a strain on actors and budget...
- and 'problems' of food and water use and limited storage need some 'explaining away' like replicators, etc...
the better 'realistic' series was Firefly - though many, including Fox, didn't like it as it looked more 'western' than scifi...
