Yeah Into Darkness was just a bad concept all around. Just a bad idea to remake a good movie in general. And then Star Trek II revolved around a villain from Kirk's past coming back for revenge. Kirk and Khan never met before in the Kelvin timeline, so there really isn't anything there. It was destined to be a a half-assed remake at the concept stage, and they should've scrapped it and done pretty much anything else as soon as someone suggested bringing back Khan.

Still it's not the worst Trek movie.
