Ok, so I'd have rated this movie lower but it really picked up after the mid part. It's intriguing, well-acted and simply engaging. My biggest complaint is the fate and substance of the CCTV footage- we saw a bit and it figures why they're hiding it, but overall I didn't understand if it did capture the killer or not. Why couldn't the defense demand it? It was not listed as evidence but there were witnesses who informally testified detective Lee demanded it. He was not going to be allowed as a witness but there were others who could testify and cast doubt on the prosecution. I still can't say I know exactly what was on the footage except for the little we were shown where we find out why it was hidden. It was made confusing and should have been clarified better. Moreover the entire timeline of the murder was confusing too. I couldn't say how things unfolded with any precision. I have to rewatch to see if I missed something. Jang Hyuk hairstyle is way too hip for someone in prison. Other than that, enjoyed both the acting and the intrigue. Solid movie out of south Korea!
