Japanese Movie '' In Love and Deep Water '' is a romantic comedy/ cozy mystery. It takes place on a cruise ship where two people who had been cheated by their partners witness a murder the victim of which goes missing.

The movie tries to blend in two things, the mystery-crime case and the love story. However, as it is a movie, it doesn't have enough time to have them both developed nicely. Thus, both of them end up half-baked.

However, the story isn't that bad. The mystery is indeed intriguing and, in the end, I do wish that it was better presented, as it had lots of potential.

The love story was cute as well. From the prompt that brought the two of them together, to the progress of their relationship, it was enjoyable to watch, and it would have been great if they had more time. The couple had chemistry as well, which helped with the enjoyment of the romance.

Finally, the performances were great by everyone in the cast and, especially, the kids!

So, overall, six out of ten.
