Well, he did as good as nothing in his time as an Avenger, for that I have to give him a 1
BUT: for the potential, Gilgamesh would have under the right writer, I would give him a 9. Always liked this character and still hope, he will be back and shows Cap, Thor, Iron Man, Hawkeye, Hercules and others what he can do as an Avenger!!!
Isn't giving marks for "potential" like giving trophies just for participating?
I've never liked him, but I'm always willing to. Ever since the original Eternals series, it just seems like his role is to be Mister Meh.
