Starscream on Robots in Disguise
I stopped paying attention to this show when they cut season 2 short by 12 episodes.
And then they make a six ep mini, and confirm season 3. No idea what changed, but these six eps call back on Prime much stronger then past seasons.
Dark Star Saber, Starscream's flashback, a return to Prime's base, and Optimus even has his jetpack again (He FELL OFF A CLIFF in season 2, so the writers either forgot about it or chose not to include it.)
