It would be dumb. If they stated their view of it without seeing it. They actually stated no view at all.
So, you stated :

More likely, you are an energy vampire, and in that case. Well done. Because your two comments are two of the least intelligent I have ever seen. And.. if you are legitimately not trolling and are trying.. I weep for the caretakers who will wipe your butt and feed you.
It was actually incredibly powerful. The first episode or so is dumb in the way that only Korean films can be. But if you allow yourself to be sucked in, you're in for a wild ride.

Popular things can still be entertaining, just look at the original Star Wars for instance. You can always give it a shot, sometime. Also, expectations can sour an experience so try to be open and everything, especially considering where you're coming from.
