What's missing, I feel, is the ultimate conclusion to this guy stalking this girl ('Hey, I know we just met, but I secretly took not just photos of you but also video! Check it out!'), which would be later in the hotel room when (after he answers in the negative when she asks him 'Aren't you going to take the watch off?') he makes his own x-rated clip of her and spreads it on the internet, becoming a hot topic in Samsung-friendly news outlets in Korea (ie. all of them).
The comments are, to put it nicely, unsupportive of the ad, calling it 'creepy' and such. Come on, non-Koreans! Please try to understand that Korea is home to sayings, as James has noted, such as '"열번찍어 안넘이 가는 나무 없다," which roughly translates as "There is no tree that can withstand being chopped 10 times."' (Though, to be fair, this comment should be read in tandem with that quote.)
Still, one wonders if the old 'we know what foreigners want/like, so why the hell would we ask them their thoughts on our ad campaign' mindset played some role in this just plain bad ad.
