I do think that Back to Earth bunkroom set is quite underrated. Lots of nice detail and (although I can obviously understand why they got rid of it) – the giant window was a nice touch that sold the idea that they were actually in space.
The X/XI/XII one is great but I like the delineation between the clean-ish living quarters and the grimier industrial areas of the ship.
They probably decided it wasn’t worth the expense paying for an animation for a computer screen that would only been on screen a couple of minutes out of the whole of BtE.
I really like the bunk set as a set, but think it’s a little too white and sterile for Red Dwarf. Sort of reminds me of 2001, or the TOS Star Trek movies, where everything is sleek and lacking in character a bit.
It doesn’t have that submarine feel Red Dwarf should have for this big, old, bulky mining ship.
the BtE bunkroom looks much more like a place somebody might actually live in though. the X-XII bunkroom looks too industrial imo, it resembles an engine room more than a place human beings would sleep in.
