I rarely come here becasue I'm really an in-betweenie, consistently scoring halfway between the average NT and the average Aspie in online tests. But, I thought I'd post here to offer somehelp. Becasue, I can remember mimicking Peanuts as a kid.
It was really helpful - for one thing, you can see facial expressions and things in the comics like that and sort of gauge what is going on. Fussy people, for instance, will act like Lucy; to this day (and I'm 38), I dont' like it if a person is being really loud and irritated, adn what seems to be nothing, but I cn cope becasue I imagine myself in a Peanuts strip and picture that person as Lucy. (I will, if it's someone I know very well, jokingly call them "Lucy," and they tend to understand, or at least interpret, that I'm just having fun with them.)
I find TV works sometimes, but not really well. Where it works for me is giving me a few more characters where I can say of a real person, in my mind, "Okay, I know how to think about this person, he's got this characteristic of A, this one of B, a few of C, etc."
So, I guess you can say TV is something I've used to understand others, more than to mimic.
Another reason the comics might work well - if the problem is all this stuff coming at you at once with no way to intrepret it all at once, you can immerse yourself gradually. You can see the expressions and sort of start to get those without having to put tone, etc. along with them, unless you want to. (NOt that it isn't obvious even to those with much worse AS when Lucy shouts "You blockhead" and the person does a somersault from the shock
