I'm guessing that on forums like these everybody's probably reviewed every episode, but if not, here's my half-year take on the first three North American Transformers cartoon series.

100 Days Of Transformers
Covers my thoughts on The Transformers, plus Scramble City and The Transformers: The Movie (1986).

80 More Days Of Transformers
Covers my thoughts on Beast Wars, Beast Machines, and the two live-action movies. (I finished writing this just now.)

I don't know if I really want to tackle Robots In Disguise next. Someone convince me to do Transformers: Animated, maybe...
