I wanted to review this show because its actually one of my favorites. I began watching for Lee Jong Suk and was pleasantly surprised when I realized f(x)'s Krystal was in it as well. I'm a big fan of both their work and was very happy that they were both in it together. The show also introduced me to an abundance of other actors/actresses who I thought did a wonderful job with their roles. I adored all of them and look forward to watching other things they star in. The first thing you should know about this show is that it's a sitcom. It's basis is humor. Different types of humor don't apply to everyone so its really a hit-or-miss with each individual. I myself wasn't sure about it in the first couple of episodes. However, as I continued to watch, I found myself liking it more and more as the characters and plots developed. The story follows the paths of many characters who all intersect with each other dealing with a variety of things like school, work, family, and romance. I thought it was great it all aspects including the music, acting, and story line. Though I love it to pieces, I gave it a five for rewatch value. Not to say it isn't good though. I gave it a five because of the amount of episodes. I wouldn't sit down and rewatch all 123 episodes, but I would catch an episode or two if it came on. That's the great thing about sitcoms, if you're familiar with the characters and story line, you can technically pick up anywhere to rewatch! I haven't seen "Unstoppable High Kick" or "High Kick Through the Roof!" yet so I'm not sure how it compares to them. However, if you're a fan of comedies/sitcoms, I'd definitely recommend giving this show a go. :D
