Familiar Wife was the only then-airing drama that I was waiting for every week. This, if anything, indicates how this show is captivating, though it isn't flawless, especially if you keep comparing it to Go Back Couple. Believe me, they have the same theme, but have different treatment.
The 1st episode is a copycat of Go Back Couple's. But from 2nd episode onwards, you'll realize the difference.
The plot itself is very real and depicts marriage life and personal flawed traits within a fantasy frame. The time travel theme is here just to serve the thought of "what if". Everyone face a debacle/s in his own life and wishes to reverse things back, but going to the past is not always the best thing.
The characters are flawed and not so likeable, especially at earlier episodes, but they soon grow mature and that's what makes it relateable. The protagonists needn't always to be angels and saints. The characters' behaviors are consistent from the beginning till the end. I love it when the writer knows what to do and doesn't drive me to wonder why.
All actors here are excellent at their job without exception. Ji Sung never fails, especially at emotional scenes, but Han Ji Min here is the show stealer. She managed to move from one mode to another easily, keeping her charm and electrifying chemistry with Ji Sung.
OSTs and BGM are melodious and fit the scenes well. My fav is Let Me Show You. It's real fun.
I'm glad a lot of current dramas care about cinematography, and FW is no exception.
My only complaint is about the fillers. There are two needless cameos and a lot of office scenes that I had to skip.
One last thing, This show kept surprising me. I never knew where it was heading to and had some good cliffhangers.
