My DVD player was out of commission for a year and I finally got it replaced, so I'm finally caught up with Season XII. I'd say that it's better than Season XI but not as good as Season X. Just as I prefer the claustrophobic bottle episodes of Season I over their later Starbug adventures, I think that Season X was the best of the new batch because they had so little money.
As for Season XII...
I really enjoyed Hitler in "Cured," as well as the poker scene at the beginning.
"Siliconia" was decent if only for seeing the rest of the cast doing their best Kryten impressions.
"Time Wave" was probably the weakest episode of the season. As a satire of modern political correctness, it's pretty thin. And given how much of the show is traditionally based in insult humor, it didn't really give the regular cast much to work with. And we've already seen episodes with physical manifestations of Rimmer's inner demons in "Terrorform" and "Officer Rimmer." Still, I loved the bit where Rimmer starts to quote a Space Corps Directive and then cuts off Kryten before he can correct him.
After sitting through 2 years of the lazy Trump-bashing that passes for political satire these days, "Mechocracy" was a refreshing throwback, a timeless spoof of the process rather than the specific personalities. (Granted, there may be some more pointed jabs at specific British politicians that I didn't catch as an American, but I think the archetypes are pretty universal.)
"M-Corp" didn't completely work for me. And I thought it was weird that they would put this episode right next to "Skipper" when both episodes have major moments of Season I nostalgia. I would have spread them further apart.
"Skipper" was my favorite episode, mostly because of Mr. Rat. I knew that it was Danny John-Jules based on how well he moved in that rat suit but I was stunned to find out that he did the voice too. He sounded so different. It's just such a surreal moment that I find myself randomly laughing about it in the middle of the day. "Would you like some cheese sauce with your cheese?" "HELL YEAH!"
It's fun to have Holly back but the lighting on him was atrocious. He looked like Darth Vader with his helmet off. Rimmer looked pretty bad too in the alternate universe where he was the computer. Couldn't they have come up with a warmer, softer lighting setup? Or else shoot him at a lower resolution? Still, I always miss his deadpan delivery. "When is this? Where am I?" "It's Monday and you're in a corridor."
