I would of much rather preferred Angela to still be an Angel, even if she had to be half Asgardian. Her debut in Guardians of the Galaxy implied she was an Angel when they had no pre-existing data on her species. I don't like her being an Asgardian, but I do like this mini. So I'll keep reading.
Except that wouldn't have made sense.
Angela being Odin's and Freyja's daughter was the best choice.
