For me, Circle was disappointing. The first half of episodes especially were quite weak and I was considering dropping it at many times. I decided to keep on watching because of the great acting and cast, despite the poor story which I felt was really boring (and when it was enjoyable I kept on finding little plot holes). I'm glad in one way that I kept on watching because the characters were interesting enough for me, which meant that by the end I was more interested with what was going to happen to the characters compared to the actual story.

I must admit however that the second half of episodes were stronger than the first. This drama mainly is split into two 'different' parts. For pretty much every episode, I preferred the second part over the first. I also liked the moral questioning of the technology and I thought the OST was nice, although there were times when there was too little, and then times when there was the odd placing of music.

Re-watch value is extremely low here, but it's because of how boring I found the story. The acting by the cast however I really did enjoy.

I think it's a predictable thing to say, but I do not recommend watching Circle. Yes, some great performances by the cast and the characters were interesting, but the story is simply too boring, and plot holes are present.
