While I can't speak for
@Frank one of the major things that missed me off about the trailer was the appearance of Data at the end. Not because Data is a bad character -
Measure of a man was a Data centric episode which was the first truly great episode of TNG, one of the best episodes of not only TNG but of Star Trek as a whole, and arguably one of the greatest episodes of any TV show.
Unfortunately Data's story was told. It was resolved. And yes Nemesis was a terrible movie & the way Data was killed off in that movie didn't make sense...but he died. He chose to sacrifice himself for what he saw as the greater good, and to undo that just because you want to bring back a popular character I feel is insulting to the character.
Of course if it turns out this isn't Data - if it's b4 or a hallucination Picard is having then ignore this. Although it still doesn't fix the problem that Data is an immortal unchanging Android who doesn't age and Brent Spiner is not.
