This should have been just a movie. Finishing it felt like a task. Woo Seok is not yet a great actor, and I kinda rooted for the second lead more since Song Geon Hee was the more charming character. Kim Hye Yon acted well. I can't blame her for her less than stellar character. I know time travel is the trend nowadays, and that's fine with me, but the I had to turn my brain off so as to not get offended by the time travelling logic. I watched this with my wife because it's one of the top rated dramas "of all time" on this site. Never again will I trust a less than year old drama in the top 10. There needs to be more reviews to knock this down the list.
