"Boundary" is touted as a Thai political film mainly because it tackles the Thailand and Cambodia border dispute. This documentary is an eye-opener as it is relevant and viewers become aware of the central issue amidst a background of electronic and indie rock music. It is interesting to note that Director Nontawat Numbenchapol created the film by chance during the New Year Celebration and this went on  to open the Salaya International Documentary Festival in 2013. Cinematography is commendable and viewers can pick up insights on some pressing issues from this docu film.
