Well, I'm a little bit like that. It usually gives me so much to think about when I try to decide what to watch next :D I often have a next drama to watch on my mind when I'm almost done with the previous one but then I do not necessarily watch that drama.
I'm the type to watch one drama at the time, sometimes multiple dramas. I usually can't watch the whole series in one or two days because I wanna enjoy it for a longer time and I easily lose my focus or get bored.
