Shoujo/drama not being my genre (being a guy and all), it is thus quite surprising for me to consider this as my favorite manga. But something about it makes it a very special, and very touching story for me.
First of all, this manga should be appreciated as a coming-of-age story about the female lead. I can understand the complaints about certain aspects of the manga, such as the art, and the sometimes cliche premises and actions. However, those aren't the drivers behind the manga: the character evolution is the true gem here. The range of emotions Yuri goes through throughout the story is amazing, and to see her overcome her obstacles is the ultimate prize. Her character is outstanding: she is strong in spirit, and yet fragile at heart; she is cunning at times, impulsive at others; she stands out as a godlike figure, and yet it is the human in her that is her most endearing feature. The 28 volumes in this manga are really just about her, and her only.
Red River is also the most touching love story I have read to date. As the manga progresses, it becomes obvious that the strength of the love shared between the main characters is unbreakable, almost to the point of envy. Is it cliche? Perhaps. But all love stories are, because the vehicle behind them is the same. The only difference is in how it is told, and Red River does it best.
Aside from the romance, there are so many other emotions involved in the journey that it amazes me. Yuri's character is the ultimate story vehicle, because the numerous choices that she makes, right or wrong, never fails to bring her to a new place, to a new meeting, and of course, to new emotions. The readers are taken along for the ride, and for a surprisingly short 28 volumes, we are there with her, facing her obstacles, experiencing her love, and living her adventure.
While there are many mangas I like, this is the only one that I have read and re-read countless times. I would certainly recommend giving this a shot, for 5 volumes at least. Then you can decide whether or not it is, as I believe it, one of the most charming and captivating stories you have ever read.
