I would like to have seen just one---ONE---of our "heroes" in AbramsTrek suggest that they do something to undo the countless loss of life caused by the villain. In every other time travel movie that I've ever seen, the heroes actually try to undo damage done by bad guys. I don't think it's asking too much for my heroes to behave heroically.
The thing is with AbramsTrek, they were trying to avoid the reset button, which plagued the last Trek shows. Then there's the fact that being able to travel back in time and fix things pretty much makes the events of the story utterly pointless.
Personally, I think ditching time travel in almost all scifi franchises would be a great thing, because it opens up plot holes as to why people don't use it to fix things, even when it's been proven that things will not go to shit if they use time travel.
