there are 2 things; one, the director had a vision of weirdness they wanted to express so this felt like an independent film rather than a drama, and I feel like the plot lost substance trying to achieve that vision.
and two, I don't know what they teach to all korean writers but they cannot explain their plot in less than 16 eps and they need 100 side plots to distract people from the main plot, so in this it felt like they had a 16ep plan that got reduced and they just picked random events fit the drama.

I'll cut this into 2 story points too,
one is the main plot around the fl and the ml which was ok, they explained well why she used toys and they even gave her a nice solid base that didn't feel flat. she had a past and she didn't just "start" when the drama began, most stories do that they give us a written back story and the main character starts from point 0 when the drama starts so they are as clueless as the viewers -which might have it's charming points but it's over done.
she had friends and a life around her and I really liked her arc with the friend though again like everything else in the drama it was not used well. also she cried weirdly alot, they literally had her flop down like a 5 year old and cry ;)
on the other hand the ml felt flat, he didn't have much base and he just felt like he suddenly manifestation for the fl's story. he didn't have much characteristics, friends or a life outside the fl..

and the other part is the kids..
I feel like they were the weirdest thing, their stories were weird, their actions were weird that they felt exactly like the jellies, they were floating around with their plot moves as if they too only existed for the fl's arc



my favorite part and character was Mr. Mackenzie, not because I'm biased with yooteo, but his character added conflict, mystery and depth to the story. though I think he just disappeared, I didn't pay too much attention to the last two eps..


for acting I think both mains did a better job than their previews works, Jung Yoo Mi was less awkward than her character in live and Nam Joo Hyuk finally broke away from the teen roles they forced him on, he really felt like a nice grownup.

the music was as weird as the flavor of this drama but it was nice and I never rewatch stuff.
