Although "Little Big World" is more like a documentary, whereas "On Cloud Nine" is a fictitious series, they both celebrate the beauty of Northern Thailand. The setting of "On Cloud Nine" contributes a lot to the mystery of the plot, and Phuwin and Pond show viewers how to experience this kind of magic themselves.
"180 Degree Longitude" is not the typical Bl series, but tells an unusual story involving a gay relationship of two men with a remarkable age gap. "On Cloud Nine" is an unusual series, too, and it isn't a typical BL series either, although it centers around a love story of two young men. Both series have an unusual topic, and an outstanding quality of directing, editing, and cinematography.
Both "Once in Memory: Just found Love" and "On Cloud Nine" are Mindtrio productions, which means that they are high quality. Rossi stars in both (in "Just found Love" Non is his co-star, and he is just as brilliant as Rossi), and Meen, who stars in "Cloud Nine", directed "Once in Memory". Mindtrio have taken the BL genre to a higher level.
