I think you've hit the nail on the head. They keep trying to recreate the 60s stuff which was never that great to begin with or recreate New Teen Titans and the Judas Contract instead of going a new direction. I think what they need to do is keep the current line-up, age up Rachel a few years and move her and Starfire to the Titans and go an entirely new direction. No Titan's tower, no T-jet. If you reintroduce old villains like H.I.V.E., Brother Blood, or Trigon amp up the threat to the 13th degree and quit trying to recreate pizza parties and pillow fights.
