Don't expect to enjoy this unless you are a Cassie. It has quite the thin, holey plotline, makes very little sense, and is all around a bit silly. However, the cast of course is very nice to look at and if you already love DBSK then you will enjoy spending a little over an hour ogling and laughing at/with them. The acting is not terrible so much as the story is poorly constructed, so it is not horribly painful to watch (the strongest actors of DBSK get the lead roles, so that helps) but don't expect the feeling of "what a great movie!" after watching so much as "that was kind of amusing!" The best part, without a doubt, is definitely that the OST is 100% DBSK :) And of course, no matter how their acting skills may be, no one can deny their superior musical talent, so that is definitely a plus.

Overall, this was not -so- bad, and it was an entertaining way to waste some time, but unless you are a diehard Cassie or are just curious about DBSK, there are probably better things to watch out there.
