I thought the trailer of this movie looked amusing, and I suspected from the feel of it that it would be funny and maybe even cool to watch. We finally watched it this evening, and wow, what a surprise, thank you instincts! What a treat. Yes, the movie is light, sort of a darkish action sci-fi comedy, and super cool. That was all we wanted tonight, to laugh and escape. But this film was much more in many layers beneath that. The director has serious talent and creativity, he takes you on an adventure in ways you just haven't seen before. So refreshing in this formulaic time. This movie features excellent acting, cool and funny effects, deft attention to detail (it's really like a trip to Korea), and a gentle touch that nuances every character so that you see that everyone is trapped in an intertwined set of dynamic forces, nobody is purely good or evil, just human. The film clearly reflects a love for Korea--the good and the bad--and does all this while taking you on a fun and outrageous ride.
Now I see why I liked Train to Busan so much, the pattern is clear. Yeon Sang-ho is clearly a rising film talent, in that movie he actually managed to make a zombie movie feel simply plausible, another day at the office, and managing to make me laugh at what otherwise were the most gruesome moments. This is serious talent, and I look forward to watching all his other prior and future films.
