Animated... short-lived, but one of the more popular and expansive Universes in Transformers.
Details of the Animated era can be read about here.
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
