To me, it means viewers disliked the last season they watched but hung in through to end, in hopes for something good. It didn't deliver, so they didn't bother with the next season.
This is based on my opinion of the above said show.

I blame Neal Stephenson for this, both in why I spotted the things that I did and where a lot of S2 came from even though it felt so left field for the average viewer.
(I tend to refer to S2 as the "Futurama's Robot Church" season and think it makes a lot more sense when you see it as a struggle between the Robot God and the Robot Devil, and the Robot Devil is not who most people think it is despite S1 laying out a lot of hints.)
