The premise is so wildly implausible that it seems like there is no way they could make it work, but Castaway Diva is a very pleasant surprise. It is every bit a showcase for Park Eun Bin and she pretty much knocks it out of the park--and this right after her star turn in the remarkable Extraordinary Attorney Woo. (Kudos to her management team!) The supporting cast is quite good too--especially Kim Hyo Jin as mentor Yoo Ran Joo. The plot has some pretty glaring holes, but just go along for the ride. It's worth it. Good, not great, but definitely worth a watch for fans of "plucky, down on her luck girl makes good" kind of dramas.
