I think Marvel REALLY messed up on The Sentry. Love him or hate him, personally I'm neutral when it comes to him, Marvel made him to be their Superman. I have the entire Marvel Knights series where he first appeared and I love that series. It really is the definitive Sentry story and it really does make Robert Reynolds Marvel's Superman in a certain sense, willing to sacrifice himself once again and have friends forget he ever existed to keep a massive threat at bay. This truly was the ONLY time I have enjoyed The Sentry
Then Marvel tried to bring him back. Now I didn't like this one bit as it defaced what I thought was a very well told story and ruined a what I thought to be a very noble character. Marvel made Sentry an emotionally unstable, extremely powerful character, and then had no idea what to do with him.
Now, how could The Sentry have been saved? For one, I say have Robert Reynolds overcome the Void, but it ends up taking a living form. This causes their power to split and thus bringing them down to manageable, yet still powerful levels. Still powerhouses, but not to the planet threatening levels we've seen before.
This would make him one of Earth's strongest heroes and given a new powerful villain. Could this have saved The Sentry?
