Watched this on a lazy Sunday afternoon when I didn't want to engage all four of my brain cells at the same time... Just what the proverbial doctor ordered.
Cinematography excellent, CGI's very good... Simple plot based on a fair amount of Asian tradition and imagery, smattered with a heaping dollop of slapstick.
The comedic chemistry between the two main characters is what you'd find if you looked up the word adorable in a Korean dictionary...
Oh and plenty of action scenes that blend in almost seamlessly... This is a very strong six for me... And OMG the whale did a fantastic job I can't say enough
