Very underrated but one of the best KDramas I've seen. Cleverly, intelligently written. Hilarious and funny but serious and thought provoking at the same time. Fast paced. Gets more interesting in each episode.

Great leads and supporting cast. No nuisance characters or substories like in other KDramas (acting as fillers or extenders) to make it to 16 eps. Everyone, everything in Legal High has his/her/its place.

Lots of sudden twists and turns. Some are quite hilarious.

Great visuals, too, cast, setting, locations.

Jin Goo (Descendants of the Sun second male lead) and Seo Eun Soo (Dr Romantic) are perfect for their lead roles, especially Jin Goo. The supporting characters are also very remarkable especially the elderly man playing Mr "I once was...." Gu.

And that episode 16 dual court room scenes are so well executed.

Lots of genres represented. Mainly legal and comedy, with a bit of action, drama, romance, medical, paranormal, crime/investigation.

Among the Legal KDramas (or KDramas with court scenes) I've seen, Legal High is now on top of my list, because it really is fun to watch.
