It's hard to rate it because I didn't hate the show but I didn't fall head over heels for it either. The concept is interesting. The male lead has a special ability to reconnect and heal it's broken parts within seconds. It's a lot like Venom (which I loved) but much more bloody. One day he is just walking along humming a song he wrote when he gets himself kidnapped by organ harvesters. His eye balls get removed but he manages to wake up and plop one of them back in before bolting. Meanwhile his other eye gets placed in the head of another man. The male lead starts to see visions of him and in trying to find and get back his eye, he discovers the man's secret. He's a serial killer.

Up until this point, the show was pretty interesting but it just goes downhill from there. Lots of running around. Lots of incompetent police officers which drive you nuts. SO MUCH GORE. If blood and torture and dissection of bodies bothers you then you will probably hate this show as there is a lot of it from time to time. I just about managed to make through it by watching it in 2x.

I did love the visuals of the connect. The CGI was top notch. I enjoyed the intro theme. Looks beautiful. The main song also really grows on you. There are some action sequences that I enjoyed but too few to really enjoy. More of it would have increased my rating. I actually enjoyed the serial killer aspect to the story because without it, there wouldn't have been anything interesting about the story.

However, the twist related to the serial killer was just a little too much. It wasn't needed in fact. And if anything it made the story a little over the top. There's also an unnecessary sex scene in episode 2.

MAJOR SPOILER ALERT
I also found the end frustrating because when you are trying to escape a building, you go down and not to the roof.

Overall, I thought it could have been improved in several ways which is probably why I wouldn't bother rewatching it. But it's fine for a one time watch being such a short show.
