I am fond of the sci-fi tech concepts, but I am 'picky' about them. Lots of sci-fi's have good concepts, and also bad concepts. My ideal space-based sci-fi universe would contain a modified Star Trek (TOS), and a modified Lost In Space (TOS). The best way to combine those would be in a Forbidden Planet universe - from which both series concepts germinated. Of course it would not be creatable by contemporary Hollywood. And it would not be marketable to contemporary 'target market' audiences. But, I like to play with, and discuss the concepts anyway. Picking the best of each, and pinches from others.
Of Star Trek (TOS)...
I like:
* the Enterprise interior - but Uhura's communication station and the turbo-lift need to be position-swapped.
* the Enterprise exterior - but the deflector dish needs to be removed.
* the matter/anti-matter ship's power source.
* the ship's phasers.
* the crew uniforms - style and colors.
* the hand phasers, tri-corders, and communicators.
I don't like:
* the exclusion of flying saucers and robots.
* aliens in the Federation.
* aliens everywhere.
* the shuttlecraft - they should be small flying saucers.
Of Lost In Space (TOS)...
I like:
* the Jupiter-2 exterior and landing legs.
* the Jupiter-2's energy glow at Earth lift-off.
* parts of the ship interior: the freezetubes, the caged-elevator, the airlock chamber, the many switches and colored lights, the main viewport window and crash shields, the brightly-lit interior, and the over-all beige and brown color scheme.
* the Chariot - but the top-side radar dish, solar panel, and dome need to be removed.
* the series concept of a civilian family, lost on an alien planet.
* the bold colored crew outfits.
* the jetpack.
* the Robinson family and ship pilot Don West.
I don't like:
* Dr. Smith - I hate the existance of his character in LIS!
* disregard for intellegent credibility.
* progression to increasing campyness.
* the lack of other families aboard the Jupiter-2.
* the Jupiter-2 is too small for it's interior and cargo.
* the season-2 flight console.
* the season-2 faster-than-light ship speed.
* the season-2 departure from Priplanus.
* the Spacepod.
