Into Darkness had more flaws imo than Nemesis. At least it wasn't a remake (a reverse one, granted with Into Darkness), along with acting that wasn't even good at all by a lot of the cast.
Actually that what I think of NEMESIS.
But I really don't mind the 'remake' of TWOK with Data sacrificing himself for Picard all that much.
Its just a shame to me that Data had to die. I wish it had been Riker instead. LOL.
You see I have this vision of Data surviving through the years way after TNG. And linking any future Star Trek series with the past.
