Stuff I liked: How Sky Lynx redeemed himself and everything leading up to the redemption; Ravage ejecting, transforming and scratching Scorponok's visor.
WTF: 30 seconds spent on Earth's surface in a miniseries titled "Earthrise"....?!? Siege Season 2, maybe. Just a minor nitpick; I expected a few more of the Earthrise toys to show up, and there were a few inaccuracies (e.g. ExhUast's head).
Overall, it was a fun ride
