Very engaging, fun to watch but, yes, have to turn off science brain. (SPOILER) I was cringing when people were walking around without masks and gloves AFTER learning that colleagues died of a contagious disease. Plus the transparent helmets on the sunny side of the moon.
I've realized that Korean dramas inhabit a sweet spot where the content is fairly simple and simplistic but the execution is top notch, which makes for very easy watching. Wish Indian producers learnt something from them.
