Oh yes, I totally keep away from "Viki Originals" After I watched parts of that trilogy, "Story of the hand" or whatever it was called.
Same as web dramas. They usually suck - with few notable exceptions such as "My Only Love Song" produced by Netflix, which was surprisingly good, the sweet "Romance Blue" (2015) and "Wednesday 3:30 PM".
I believe that an actor should learn in drama school, not while working at dramas. They want to put them out there for everybody to watch their first awkward tries, why?
I mean, many of them, if not most, eventually learn to act decently (if not really well). But people will always remember their first dramas where their acting sucked.
Why waste two, three or more dramas like that and totally ruin their acting reputation? It's so much easier to 1. put them through acting lessons and 2. give them small roles first so that they will be gradually exposed to the ways a drama is shot.
But no, they have to give them leading roles and watch them make a mess out of them. Totally stupid idea.
For instance, take Jong Yonghwa. If you watch his latest dramas, he has become a quite decent actor. But everybody remembers his wooden first appearances in You're Beautiful and Heartstrings. Because the dramas were such successes too. They did him no favours by catapulting him to second and first roles immediately when he was totally inexperienced.
On the other hand, Lee Jeong Suk. He started with a small appearance as an office worker in "Prosecutor Princess". Then a small but meaningful role in "Secret Garden". And then of course the role which made him famous, in School 2013, which was bot the only lead but shared with three other actors, and also was near to his age and sensibilities, so an easy role for him to do well. From there, he became better and better, to become one of the best actors of his generation. But he went gradually, learning his craft as he went. They didn't just give him a leading role from the start.
Of course some people also have some talent than others, and some won't learn even if they study for years. But everyone would benefit from the gradual method.
Viki Originals are usually also very poorly written and directed. That's why I'm saying: away from them!
