Sentry isn't good. Stop saying he is.
Newsarama ranked The Sentry as the third worst Avengers member.
"The Sentry is the worst of the worst, and what's baffling is that there are still two characters that are even lamer.
Everything about the Sentry is terrible, from his origin as a "secret lost character," to his eventual descent into madness at the hands of Norman Osborn, and every "lost secret" in between. If Sentry had disappeared after his initial miniseries, no one would probably care at all. Instead, he forced his way into the lineup of the New Avengers, staying with the team until his death at the end of Siege.
Possessing the power of "a thousand exploding suns," the Sentry is a schizophrenic powerhouse who somehow managed to make that combination of words actually mean a whiny, self-possessed MacGuffin character whose personal lameness is only outweighed by the lameness of the conceits that are required for his existence to make any sense. The Sentry is one of the worst wastes of potential, story time, and printed ink since Tony Stark was replaced by his alternate teenage self. His only sort-of redemption has come in death, as one of the four horsemen of the Apocalypse twins. Even so, that's only because we got to watch Thor kick his ass one last time."
I think Kabam got this champion right! Kudos to them.
