First of all, there are only 9 episodes. Some comments here refer to there being 12, which might be a result of hallucinogenic drugs, no idea...
RY is very entertaining, quite Pythonesque in many ways. While not all stories are equally funny, all are at the very least interesting to watch. Sometimes weirdness alone in a comedy can keep one's attention, the (successful) gags being a bonus. "Golden", for example, is a comparatively subdued episode but has a certain charm, ditto "Winfrey".
"Tomkinson", "Escape" and "Murder" are the funniest episode, whereas "Roger" and "Frog" didn't turn out that well by comparison.
The DVD offers a relatively interesting running commentary by both Palin and Jones. If, like me, you are annoyed by left-leaning actors/directors promoting their ideology publicly, you should be warned that Jones uses any chance he can to connect what goes on in a scene to social or political issues. He is a Marxist to a fault, but I think we can forgive him for that due to his Python past and cheerful affability...
