Yeah, S8 was OK, just not a patch on the fantastic 1-5, or even the slightly less fantastic S6.
To me 1-5 is when they were "on form", it was both a great comedy and
a great sci-fi show, and I don't see it ever coming close to that sort of perfect mix again. They'd better off just making sure they come up with better plots than BtE rather than trying to be as funny as the old stuff. At least we can get some good sci-fi, even if it isn't that funny.
