Something about action dramas from around early 2010s make them unique for better or worse. The drama started off with a big bang, literally, while shoving in the maximum possible amount of flashy elements. If you watch the very first scene it should give you a good idea. However, just like other ones from around the same time, it gradually began to wither away after 5-6 episodes until it reached a bland conclusion. The male lead doubling his role as a comedic relief was mostly fine, but him flailing his tongue like a dog was a bit too cringe to tolerate. The drama really wanted to include romance because it was the trend back then, that's why we had multiple pairings, most of them were unnecessary or weak. The main antagonist was your generic baddie, the drama didn't even show him a lot until the last few episodes because they didn't want to bother with more writing. The vibes were very similar to 'A Man Called God (2010)' which came out in the same year, except this one was a bit better.
