I guess some people just can't cope with anything but the most cutting edge effects. If they notice something is fake the movie experience is ruined for them or something. I'm glad I'm not afflicted with this.
It's really a shame that Farscape didn't have stronger writing because the whole puppets and minimal effects thing works pretty well. (I can forgive Season 1 a bit as the actors and the writers were still figuring out the characters. Season 2 and forward sub-par episodes were all on the writers.)
However, as I understand it, the problem with the puppets is that they are expensive.
All of that said...
There's a certain correctness in my head to the idea that in a pre-replicator future [0], it would be more smart to use a bunch of physical buttons and CRT type monitors.
The main reason that comes to mind, is that a simple CRT is probably easier to fabricate on a deep space mission than a flat screen, if it needs replacement. Similar for all the buttons/lights/switches.
Now, it wouldn't necessarily be -easy- for a ship in deep space to re-fab these components. Thus the need for 'low-fi' graphics, since you might be in a region where the best your folks can fab is NTSC-quality.
[0] - While TOS had food synthesizers, that seems like a subset of a full replicator's functionality.
Modern high definition scans of the original film looks hilariously bad on modern TVs. It looked far less bad on TVs contemporary with the original broadcasts.
The modern HD scans of the original film look fantastic. They do, however, show how low-budget the sets were, but the detail of the original film is quite amazing, and these old shows look far better than most stuff produced in the 1990s which was done using videotape.
The best episode of Star Trek, City on the Edge of Forever, holds up today because of its story and its period sets and costumes, not its sci-fi stuff.
