Castaway Diva has everything i look for in a drama. Great actors, great story, fantastic OST and above all likable protagonists.
This story hooked me right in from the start. The pilot did a fantastic job at introducing all the characters and how they connect to each other. As far as pilots go it did too good a job with it's fantastic story and child actors. The rest of the series did not fall behind and the Finale was more than i could've asked for. A truly happy ending and a fitting "end" to all protagonists.
As far as acting goes, i've felt this before with Extraordinary Attorney Woo but Park Eun Bin just brings a certain energy to her characters that makes you like them and look forward to their stories. I'm not very familiar with the rest of the actors but they also did a fantastic job.
If you are in the fence about watching it, please just give it a try. I promise you won't regret it.
