I don't know about anyone else, but the reason I started watching this drama was Kim Hee Chul. Yes, I know he's not a good actor. BUT he's one of my two biases in Super Junior (Si Won being the other). He's also the reason why I even gave the group a second chance. "Sorry, sorry" is just not my thing... Sorry! Not really. I also like Lee Soon Jae, I think he's one amazing veteran actor. To my surprise, "Flower Granpa" was really funny. I enjoyed it so much that I went through the first seven episodes really fast. The premise was also interesting and I liked that all the grandpas had their own concepts. I called them "grumpy grandpa", "cute grandpa", and... "delusional grandpa". And while Hee Chul and Lee Soon Jae were the main driving force which made me watch this drama, I ended up loving "cute grandpa" Kang Seuki the most. Although, it was kind of hard watching a grown man, who is old enough to be my father, around so much... pink. Did I just show my age? Jijiji. But as it was nearing the ending episodes, it kind of went down a small hill. The story got rushed. The things Lee Joon Hyuk, grumpy grandpa, started to do made no sense at all. I mean, come on! He's supposed to be a smart police detective! I can't really say much more without adding a plethora of spoilers. Another thing which bothered me was the "main villain". Although I have nothing against the actor who played him, I thought he was too mellow. He didn't give me that "I'm a mastermind" vibe. I just wanted to smack him over the head and tell him to "straighten up" as if he was a teen misbehaving. I just couldn't buy him as a villain. *shrugs* Although I thought "Flower Grandpa Investigation Unit" was really light and funny at first and I really enjoyed it, I have to say I was somewhat of disappointed with its last episodes. It became too over-dramatic and rushed.
