'Descendants Of The Sun' Star Song Joong Ki Criticises His Own Performance: 'I've Been Seeing A Lot Of Room For Improvement In My Acting'

The South Korean television drama "Descendants Of The Sun," which premiered on Feb. 24, may be receiving such high ratings and the Chinese government to warn citizens that "watching Korean dramas could be dangerous, and may even lead to legal troubles," according to CNBC.

But Song Joong Ki, the 30-year-old star of the series, still wonder if he could have done a better job on the show, which he called "the best screenplay he's ever seen."

"I've been wondering a lot lately whether I did the script justice," said the "Descendants Of The Sun" actor in an interview Wednesday with South Korea's Yonhap News Agency.

"Despite having had plenty of time to prepare since the series is entirely pre-produced, I've been seeing a lot of room for improvement in my acting."

The preproduction Song referenced is the practice of "early filming," or shooting sequences ahead of the rigorous production schedule all South Korean television shows are forced to follow, still a relatively new technique for the genre.

However, that might be about to change following the blockbuster success of the television show "Descendants Of The Sun," a program that reportedly relied heavy on early filming to achieve its ambitious scale. Last Wednesday's episode of "Descendants Of The Sun" received nearly a third of viewers in its 10 p.m. slot according to Nielsen Korea. It has also racked up more than 120 million views on the Chinese online video platform IQiyi.

"There were early filmed dramas before us, but they were largely made before they secured a broadcasting time and were weak on casting, lacking star actors and actresses," the show's producer Bae Kyung Soo told the Korea Times on Sunday.

And though the show may shaping up to be a mammoth hit both inside and outside Korea, Song is still skeptical of the news reports about China's "Descendants Of The Sun" obsession.

"I can only guess [at how famous I am there] from media reports and messages from my friends in China," he said. "I don't think greater popularity abroad would make much difference in my life. Currently, I'm focusing my efforts on preparing for my next work."

New episodes of "Descendants of the Sun" air every Wednesday and Thursday at 10 p.m. on the Korean Broadcasting System KBS2 network.
