I don't care or worry about popularity of any drama. Somehow I think good critical reception is just as or even more important. Gong may be popular but it will never be a classic because it was critically panned and puked on, plus most people seem to have bad memories of it. Look at how fondly remembered the original HZGG was as well as Yongzheng Wang Chao. Now those are amongst the great classics of C-drama to be remembered and loved forever. BBJX the Novel already has that position, so I hope that they will pull every stops (now that they have time on their hands) to make the TV series a classic in every aspect, especially the music score. I really think a great music score is really important for that fond remembrance factor. E.g. to this date, my Mom can still fondly hum every tune from TVB's original LOCH and ROCH adaptations in the 1980s.
Anyway, I think most dramas aired on Hunan TV are guaranteed popularity anyway. I just came back from a stay in a remote rural village in Dali where the only TV channels available were CCTV and the local Kunming station. And for Hunan TV's drama viewership to even surpass CCTV's which has tentacles that extend everywhere, even to the most remotest of rural areas - that says A LOT!
