Gotham Netflix recommended value? Should have asked?

I have just seen the first episode quite nice but I could not explain some questions

i thought jason gardon would be barbara's father (adoptive) and not the wife. So I know it from the comic
why is the penguin thin and tall, which must be fat and small

So if you mean James Gordon: His wife and daughter are called Barbara. And as for the penguin?!
He does not always have to look the same in every adaptation.
