Couldn't believe the comment in one other review: " Asian men are never portrayed as the central love interest, or god forbid SEXY." Then I realized that the review was written 7 years ago... and in America.
There are now sooooooooo many fantastic Asian films with Asian men as the central love interest and unquestionably they are overwhelmingly,devastatingly sexy, which is more than can be said for this crew. More importantly the films are interesting, well-acted, well-directed, shot in the real world (as opposed to someone's basement) and did I mention, well-acted.
Most of these far superior movies were produced in Asia, for example, Soundless Wind Chime, 15, City without Baseball, Eternal Summer, My Fair Son, Bangkok Love Story ... to name a few. Not high budget, but beautifully presented and with meaningful stories... and with high quality acting even if the central characters are amateurs or even just kids off the street.
Under One Roof is like a badly acted '50's soap opera or a high school production. I'm not sure which is worse, when they appear to be reading their lines in monotones or when they suddenly try to add some (generally inappropriate) emotion while reading their lines. The main character seems to only employ annoyed whining as his style, no matter what the situation. There is no sense of interaction between the actors.
I can't imagine that even 5 or 10 years ago this would have been more than an embarrassing amateurish production.
