You know a drama's good when it makes you cry. You know it's excellent when it turns you into a snivelling wreck every single episode. Thus, my main issue with Mother was what it cost me in Kleenex. The most devastating thing about this drama (and there are a fair few to choose from) is that you know there's no way it can end happily. It's very premise sets it up to have at best a bittersweet ending.It is extremely well written in this respect, and believable throughout. I found myself truly invested in the characters and the storyline, desperately hoping both Nao and Reina could find safety and happiness on a more permanent basis than constantly being on the run. I would now spend a paragraph picking apart the faults of this drama, except I'm rather convinced it doesn't have them. Everything from the acting (Ashida Mana may have become my favourite child actor of all time through this drama) to the movie-esque quality to the filming records it down as a must-watch in my book. It truly is once watched, never forgotten.
