It's not about having new characters, it's about those characters specifically. I just don't enjoy them, their personalities, (their appearances aren't too bad). Perhaps it's because they're all from America, whereas the BO1 guys were from all over. Their annoying for me and I don't like listening to them talk as much as I did other characters.
I loved the original four; the "Five" four were pretty funny, not great but not too bad; the CotD four weren't the greatest but had some good lines; the Mob of the Dead characters were really great and second only to the original four.
EDIT: Also I was looking at the new Ray Gun and it reminded me of Wolf's gun from Super Smash Bros Brawl

That's kind of cool.
