The last I watched it, which might have been a year ago now, there was no humour remaining in it, and instead of having colourful situations and entertaining reactions, they had filled the show with cringy, sappy, and pretentious speeches that were, well, lame. The next season is OK, too, as something to fill the absence with, but from there it just becomes not worth watching and feel devoid of substance, humour, interesting stories. That was the last episode of RvB in its original quality. RvB has been dead since the 12th (I think) season, whenever it is that they crash on that planet and Church takes-off with Caroline and the others are wondering where they went.
