STORY: It's a very compelling story that had me interested the whole movie and it ends satisfactorily. I should point out that while the show doesn't have a "sad" ending, as in soul crushingly pointless, the overall show is a tear-jerker. Also, the show is mainly about the mother and the spirit mediums she hires, so even though there are some gay characters in this, I wouldn't call it BL.
ACTING/CAST: They did a good job. "Boy" did his part well, all the dancing and ceremony, nice job. The son is cute.
MUSIC: Ah, standard for a movie.
REWATCH VALUE: Ah, I'll probably spend my time watching other things.
OVERALL: A good and entertaining movie with some great storytelling that presents lots of questions that all get answered in the end but no real "BL" in it.
