I know Signal is very highly rated, despite Kairos and Signal having similarities, I found Signal to be draggy and not as thrilling as I suppose others found it to be. Whereas Kairos, had me hooked on for every single minute from the beginning episode, and I finished the whole series in a little more than 24 hours.

Firstly, the acting is brilliant, the cinematography is also very good. The way they have differentiated the past and the future by having past being a bit yellow tinted, was brilliant, and enabled viewers to never be confused.

The story was brilliantly executed, like every time related story, there are a ton of variables, and these variables from first moment the timeline changing continues to keep changing over and over with many unexpected twists till the last episode.

If you love a thriller, you will enjoy this series a lot, and unlike other series where we don't know the main villain till last episode, this series keeps you hooked by wanting to learn how ultimately the main leads will manage to solve everything and deal with the main villain.
