I can't recommend, it's a total waste of time.
I'm not sure what it was trying to be but manages to do nothing right or interesting enough, and acting is generally quite forced and over the top. Only FL was better and her character was probably the most interesting of the bunch but they don't dwell much in the characters themselves. ML wanted to be a butler because he likes to serve? what? haha I'm sorry, it was lame, it would have been more believable that he said something about wanting to travel, see other places in the world or even learn other languages.

The movie is boring, slow (for what is the plot) and the writing is bad. It's difficult to make a movie in a single location and for it to be engaging and entertaining enough, they didn't succeed at all in this movie.
Sub-plots are brought to the front and back depending on what is convenient to the point they feel forgotten (like the murder "mystery"). The "mystery" is one of those that seems obvious but then it's revealed to not be what you thought just for shock value and where they didn't take you along the journey at all, completely pointless. It wasn't even shocking as a reveal though, because they didn't make me care at all about anything in this movie. The crime here it's calling this thing a suspense, romantic, mystery or amateur detective movie. It's just a mush of nothingness in my opinion.

There obviously are also unresolved questions at the end of the movie, like what happened to the mother of the kid, what happened with the will in the end, what happened to the son and wife of the man that died, they might not have ultimately killed him but they were accomplices of murder in a way and of trying to falsify a will. Why are the two kids dancing happy in the end? There is just no answers.
Also, I'm sorry but that's not kissing. If they're going to make the actors "kiss" like that might as well just not have any kissing scenes, it was weird and cringy to watch.
FL arrives in the cruise with absolutely nothing, yet she manages to have a different outfit daily.

If it had been fun and entertaining I could tolerate some of the other negative aspects of this but it really wasn't, it was a chore to finish.
