Born Again was undoubtedly confusing and long and detailed and made me consider turning it off multiple times. However, it was still a very interesting and very good idea for a drama. The two male leads were total smoke-shows and I was throughly impressed with their acting skills. Unfortunately, the female lead didn't really sell it for me. Her emotions didn't seem as real and as candid. They seemed a bit put on and a bit muted. They weren't as raw as the male lead's. I won't say any more bad things about her though, as she still did a very good job and I even felt a bit of chemistry between her and Ji Cheol at the end there. I thought I was gonna have a good cry on at the ending so I was left a bit disappointed there. However, it's a good thing that the ending wasn't sad otherwise that would have been my second one in a row. Blame The Smile Has Left Your Eyes lol.
Anyway, in conclusion, it was a good drama with good acting. But, unfortunately, it wasn't a great drama with great acting.
Still, though, you might as well give it a go.
I don't think it will be a disappointment.
