cowboy bebop
kill la kill
little witch academia
scooby doo
currently watching bojack, a weird drainwards spiral of semi addictiveness.
... etc etc.

So many shows that catch my attention!
X-Files, Penny Dreadfull, The witcher, Westworld, Person Of Interest, Lie To Me are some i enjoy watching

Firefly

International? I guess It is Colombo too.

Gintama, because it's got it's humor, gut-wrenching-tragedy, horror, action, and sci-fi 😁

Actually it's One Piece again

If I think about it, it turns out that some "hospital/doctor" shows are the only long ones I have seen all episodes of, like Die Schwarzwaldklinik, ER and House M.D.
Otherwise, The Legend of Korra, and also Avatar.

Thank you so much! ^^
