Hero/Action

Like Superman, just without the superpower alien bit.  The cast, story, action, OST all came together for a kick ass drama.

Fun and addicting with off the charts chemistry plus Hyun Bin in uniform

gritty and raw with bits of humor.  lots of fight scenes

Cute and funny!  Park Bo Young is charming as always and Hyun Sik matched her spunky energy so well.  

Worth watching for just Han So Hee's fight scenes

Funny enough, I was in the minority in thinking that the Song-Song couple had little chemistry in this drama, but I still thought this was a fun drama.  When I later found out that they were together in real life, it made sense.  2 insanely good looking people having no sexual tension onscreen usually means they are dating or have dated imo.

Action was crazy good in the beginning, but the story gradually declined.

Intense, bloody, and brutal.  Awesome action and thrills

Not quite as good as S1, but still fun to watch.  Loved the action scenes in E7

The young cast really delivered on the acting and action fight scenes.  Intense, dark, and fast paced, I felt my blood boiling along with the characters. 

Finally!  A Korean superheroes drama with high quality production value and cast!

The pure message of being yourself and going after your dream is uplifting.  The cast and production value are both great.  A little campy but still a fun watch!

Fun Action comedy that'll entertain if you don't look at the logistics too carefully

Almost as equally entertaining as the first movie, Hyun Bin and Hae Jin still have great buddy action chemistry

Fresh story and cast, fun fight scenes, and a dark anti hero theme makes an entertaining ride, though the weird fade transitions in editing and repetitive scenes lower the quality some

Basically this movie is an excuse to see Kim Woo Bin kick some ass in some majorly intense action scenes.   The story is pretty surface level, but the action scenes make it a worthy watch.
