Hit K-drama Goblin is a controversial show

While Goblin is a big hit, viewers have found product placement in the series a big distraction.

In the popular TV drama series Goblin, the male lead is, quite literally, a god.

Based on the Korean folklore of dokkaebi, a higher spiritual being roughly translated as goblin, the drama series features actor Gong Yoo as Kim Shin, a warrior born centuries ago who, after being impaled with a sword, is transformed into an immortal dokkaebi with endless wealth.
