McClellan was handed an opportunity to annihilate the ANV on a golden platter and failed to do so.

Both sides gave the best they had. At the end of the day both armies were still toe to toe. All gave some, some gave all.
I would consider Spotsylvania and The Wilderness the best all-around performances on both sides of the war, at least in the eastern theatre.
