THE new HBO comedy line-up of “Curb Your Enthusiasm” and “Extras” is struggling in its first weeks.

The first season of “Curb” debuted last Sunday to just 1.5 million viewers – less than half its first-week audience for season four.

That premiere benefited from following the start of the final season of “Sex and the City.”

Comedian Ricky Gervais’ much-anticipated follow-up to “The Office,” “Extras,” which airs immediately after, drew barely 1 million viewers, despite positive reviews.
