1. Weightlifting Fairy Kim Bok Joo
2. Legend of the Blue Sea
3. Hwarang
4. Goblin
And I also think I'll really like Romantic doctor, teacher Kim but I'm still on ep. 2 so I can't judge yet
Here is how I would rate the current shows: 

1) Romantic doctor kim - it's at a very interesting point now. It has a suspence factor attached so I'm really looking forward to seeing it every week

2) Hwarang and Oh my geum bi

3) Legend of the blue sea and weightlifting fairy kim bok joo

4) Goblin - its a very nice show but somehow it's going a little slow with a lot of flash backs. 

5) Solomon's Perjury - so far it's very nice but it's a bit too early for me to judge

6) Father I'll take care of you - it's a family drama. Not really my type but I want to finish it since I started it :)
