Everyone hated it when it was standalone
Are you sure the Memory isn't Cheating there, Si? I preferred it then - Children of Earth as a 5-parter was great, but this current 10-parter is... not so great really. And Zel's given up on it entirely, yearning for the "much better" seasons 1 & 2 when it was "different stories".

Although some of the individual stories were, of course, totally awful. But not all of them. Mainly the ones involving sex-mad alien clouds. And Jack's brother.
