It seems Netflix and/or article are comparing it to One Piece numbers to say it is not doing as well.

Netflix’s live-action adaptation of the Nickelodeon’s hit animated series “Avatar: The Last Airbender” hit 19.9 million views from Feb. 26 to March 3, which earned it its second week at No. 1 on the Netflix Top 10. However, this marks a 6% decrease from the 21.2 million views it debuted with the week before, when it was only available for four days.

The viewership drop doesn’t bode well for the big-budget series, as Netflix’s largest titles typically grow in viewership between their debuts and their first full weeks of of availability. For example, Netflix’s live-action adaptation of the manga “One Piece” debuted with 18.5 million views in its first four days, then held No. 1 with 19.3 million views the week after.
