What damage? The intent was to reboot the franchise, not for the least of reasons was that all the shows and movies over the years had so confused things no one really new what cannon was. Now they have a fresh start.

As to this list I can argue with any of them (although I too really like "Relics"), and while "Yesterday's Enterprise" is probably my favorite "The Inner Light" just blew me away the first time I saw it, just awesome storytelling and the sort of story that really can't be told outside of science fiction.
