My Lethal Man is a mystery romance drama starting not well-known actors and actresses with backgrounds in supporting roles in other C-dramas.

The production quality is so bad; everything is so bright, especially during the kissing scenes. I am not sure why Chinese dramas always do that for cheap quality productions on streaming platforms like iQiyi, Tencent, MangoTV, etc.

I enjoyed the mystery aspect of the drama when the ML tried to solve the 17-year-old car accident that took his family's life. The plot was interesting until the last 4 episodes when things went wrong and stupid.
Even though it has a happy ending, the way it unraveled was so bad, and the acting was not great for either of the entire cast.

The FL does a better job than the ML, and the supporting CPs were not great. Some of the songs in the OST were good.

I am giving it a 6.5 because of the music and the first 20 episodes.
