I don't know what should I write here "about me" or maybe I am just too lazy. Anyway, here are some series I would like to suggest (I haven't watched all the episodes of some of them but based on what I have seen, they are pretty great):- 
f.r.i.e.n.d.s. 
Big Bang Theory
Pretty Little Liars: The Perfectionists (actually I am not sure if I should suggest this one, I mean, it's amazing but it ends on a cliff hanger and now they have canceled it, so... You get it, right?)
The Middle
Boss Baby: Back in business
Rupanzal: the series 
Miraculous ladybug 
Young Sheldon 
Troll hunters (netflix series)
Shadow and Bone [okay, so this one isn't even out yet, but I have read the six of crows duology, the books on which it is based on (along with shadow and bone trilogy which I haven't read btw) and they are really amazing, so if everybody does their job right then the show could be really great btw I would also suggest you to read six of crows]

I might add more to the list later.
 Anyway, be positive!  :)
