Well I was hamming it up a bit with my pretend fanboy rage, but in all seriousness, my main problem with Kyle was just the fact that he seemed like a poorly designed candidate for Green Lantern-hood. What made Kyle seem like a reasonable choice? The fact that he's an artist?
At least G'Nort and Guy Gardner were punchlines and not portrayed as if meant to be taken seriously. He was a dope, protecting the planet, wielding the most powerful weapon in the universe.
