Looks like the next two stories will be single issue stories. I want them to tell 3 issue stories but it looks like these might be lighthearted filler.
The next one is a one-issue story about redshirts
. It may not be "lighthearted" at all.
The subsequent one is the origin of Scotty and Keenser's relationship. Since Keenser is a comic relief character in the 2009 movie, that one may well be lighter in tone, but not necessarily "filler". There have been a few powerful one-shot ST stories in comic form over the decades, including several of IDW's "Alien Spotlight" issues.
Nero can still die at the end but it would have been more heroic to have Kirk trying yo save him and Nero choosing death over life.
He did and he did.
And if the movie unfolded the way you suggest, you can guarantee we'd have had people here arguing that the producers missed a wonderful opportunity for Kirk and Spock to be more vengeful after the deaths of Amanda, many starships and billions of Vulcans.
And you're never going to please everyone. (And neither am I.)
