First, you do not need to see either of the Witch movies (Parts 1 & 2). Any connections are slim and add nothing. So if you're looking for some sort of continuation of those stories you won't find it here. Instead an action thriller is served up for the first three episodes before the Sci-Fi main course gets fully underway.

I found the first few episodes hard to follow. It's like A Shop For Killers in that the viewer is thrown into the middle of intense action and in machine gun fashion the plot and characters' backgrounds are unlayered.

The fourth episode brings things to a conclusion which sets up a potentially interesting franchise led by a fascinating new main character with super powers (Venom character comes to mind).

I wish this Korean series followed the usual 16 episode pattern, because I really wanted to see another 12 episodes of a longer series. So that's my only disappointment here - that it ended just when the set up for something really good was in place.

Hopefully this was a four episode pilot for a new series.
