Circle

Ethically questionable science appears throughout both dramas, and characters struggle to find out their past through fragmented memories.

While the stories have NOTHING in common, the shows remind me of each other because they both had low budgets and yet they have been among the best I have seen.. They knew how to direct their stories to keep the audience captivated.

While Circle's genre is more of a mystery/ sci-fi drama. My love from another star is a romance/ historical genre. While the genres and story lines are rather different. The two dramas have the alien aspect relation.

Both have crime, mystery and a dash of scifi, even though circle is a bit more heavy on the scifi and quite more fast paced. Both dramas are also about people struggling against corrupt/underground organizations planning to make the world a "better" place.

Both Mistress and Circle have mystery and always leave you wondering what's next. Both have parts of the future and past shown before the conclusion. The characters are good and well-developed, smart and sharp. They work together and have interesting and great relationships.

Both are intense, thriller, time-travel dramas solving mystery and uncovering the truth behind it. Amazing story and great acting.

This drama has a very similar feel to Circle. They both feature scifi, suspense, mystery, with a bit of romance.

Both deal with the idea of clones. Both are extremely dark and messed up. I would say Duel is more messed up but the sadness aspect is the same in Circle. Both star leading actors you'll fall in love with.

Both dramas are of supernatural genre, connecting two time -present and past - to solve cases, revealing missing connections between different ppl. Both dramas have badass female leads. Worth watching. Fighting.

Both dramas are: thrillers, have plots that are told through flashbacks, and include romance.
However, Circle also has a science fiction element to its story.
