Have seen a bunch of films, TV shows, and video podcasts but haven't made the time to properly review them all so this post is a bit of a cheat. Just a simple list of what I liked, loved, and hated. I'd recommend viewing them all, even the one I disliked because it is such a strange animal, worthy of discussion.
The A.V. Club has a nice video review of this (ignore the Red Riding Hood bit)
The A.V. Club has a nice video review of this along with a feature on other Korean directors.
