But I think Waid had a much stronger grasp of what made the team function, and explored that in more interesting, resonant, allegorical ways than did Hickman. Up through the finding Ben in Heaven arc, I'd say it was a perfect run, and had a huge amount of heart.
It worked for me. As you say, she hadn't been seen in decades -- she served no real purpose, and Waid found a purpose for her. Much better than killing off a character that is a genuine story engine.I hated it because Waid brought back a character that hadn't been used in decades just to kill her off in one issue. Plus she looked way too old to be the Valeria last seen (not counting flashbacks) since IH #143 -144.
As for the rest of the Doom, it was nice to see something different done with him. It's not my favorite Doom story of all time, but at the very least Waid was taking the character into a different direction, and one that didn't end all future story avenues (COUGHMILLARCOUGH).
At this point Doom is overexposed to the extreme, and I'm quite sick of his schtick.
