Name one, just one thing that if you see happen in Transformers Prime, there is a decent chance that you won't see another episode, or at the very least, cripple and ruin your love and interest for the series. Just one thing. The biggest. It can be anything you like, but please, be serious about it. For me, it would be the death of Starscream (or his complete removal from the show), UNLESS it's done in the last three-five episodes of the series. And please, no arguments, and no fighting, no vicious comments about other people's opinions.
