Following on from the massive surge in momentum of Armada, Hasbro (with Takara) had the second chapter of the "Unicron Trilogy" released right at the end of 2003, just as the 20th Anniversary of Transformers was about to begin.

The Entire Era/Series as a whole (you can include the Japanese version if you want), how does it rate in the world of Transformers:

- Best Ever
- One of the better ones
- Average
- Not very good
- I refuse to have anything to do with it
