Really? I don't know. Better than Secret Invasion and Echo, but I'm not sure I'd call it better than any of the other series (mind you, I've only watched part of the first What If).
However, you are right, Mark isn't getting any younger, but I feel this is why they need to stop being afraid of RECASTING! Hell, some of these characters are ageless as a super power and others aren't going to get a decent story and send off if they go "Well, time to kill Peter Parker off, Tom is done with the role."
