The tv show is faithful to the spirit of the comic book.

Disney announced that there would be a"big cameo" but Valentina Allegra de Fontaine is not what I would consider a main comics character.

I suppose that is only due to the popularity of the famous & charismatic Julia Louis-Dreyfus.

I am still happily surprised that, contrary to most of his appearances in comics & cartoons, Batroc is far from being ridiculous in the MCU.
I also like that he has become a recurring character. It is a cool idea.

Oh, and MCU Zemo is still & always an excellent character.
