This drama is... a very hard drama to review. "I Miss You" is kind of a conundrum. You won't like all of it, and if you do... well, there's something wrong here. I think that's what the writer was going for here. They give you a story, but it's not sugar-coated. It's real, intense, and- most of all- unapologetic. You won't like all the characters all the time, but you understand them and come to accept them. Story: The story was painful, yes. But there was more to it than just being a tear-jerker. There was an overall hopeful vibe to it, and while the events that occurred weren't realistic, the aftermath was. While I'm writing this, I'm going to throw out that I had second-lead syndrome for most of this drama. Despite the fact that Harry was evil, I still found myself identifying with him and caring for him more than any other character. Jung Woo was a great first-lead, perfect for Seo Yeon in every way, but I still (somehow) liked Harry better. (Don't ask me why, because I have no idea at all.) The first 4.5 episodes were from when the main characters were children, and for some reason there seemed like a huge disconnect between the two parts of the story. The beginning was more... raw, I suppose. I felt everything at a much more personal level than by the time the next part came in. I guess it's because by the time the adult years came in, you just became so desensitized to the pain of the beginning that everything else didn't hit you the same way. Also, in the adult years, you don't feel as emotionally connected to the characters as you did in the beginning. When I watched the 20th episode, I was going to give this drama an 8 overall. The show was good at times, a little slow, and somewhat boring- but still good. I assumed that since the extension was given with so little notice that it would just be a filler episode, but I was proven wrong. Since I don't want to spoil anything, I'll just say this: It was worth it. The ending fit the story's tone perfectly, bumping my overall rating up from an 8 to a 8.5. This show isn't a light watch, but it's sprinkled with it's moments. I'd recommend watching something lighter afterwards- unless doom and gloom is your thing.
