"Marriage Blue" is a delightful Korean RomCom that offers a light, easy, and fun viewing experience. The movie centers around a unique concept of intertwining relationships leading up to weddings, making it an enjoyable and refreshing watch. Despite its engaging plot, the film falls short in terms of character development early on, which can be confusing when trying to distinguish between the numerous actors and actresses who, unfortunately, look alike.

The absence of over-dramatization is a breath of fresh air, providing a more realistic portrayal of relationships and romance. The humor throughout the film is genuinely enjoyable, leaving the audience with a smile on their faces. The movie excels in its portrayal of the characters, and the talented cast brings them to life in a believable and relatable manner.

Though "Marriage Blue" stands out as a cute romantic movie that offers a nice break from heavier dramas, it doesn't quite reach the level of being a groundbreaking RomCom. While the movie is fun and nicely done, it doesn't necessarily outshine other RomCom movies or dramas that I've seen before.

Nonetheless, the film manages to entertain and amuse with its charming plot and comedic moments, maintaining a good balance between romance and humor. It's worth noting that the movie takes a more realistic approach to relationships, with plenty of kissing and hints of sex, though nothing offensive.

One minor flaw is that the movie tries to cram too much story into its runtime, which can make it slightly overwhelming at times. Nevertheless, "Marriage Blue" remains an enjoyable watch, especially for those seeking a light-hearted and amusing romantic comedy.
