I'm a member of a teen writer's website called Teen Ink, and want to write four reviews for Transformers: Prime (Darkness Rising, the first half of season 1, the second half and One Shall Rise) Can I get some help with finding the midpoint?
Yes, I'd put the middle of the series as Out of His Head. Megatron's return marks a new direction for the second half of the season. Sick Mind, the first part, was also used as a mid-series finale by Cartoon Network in the UK (grumble, grumble...)
