I have quite a few for Best and Worst for my 2009

Best - MP Grimlock; Animated Season 3; ROTF (I loved it! I love seeing TFs battle it out at famous landmarks ); Alternity Convoy - a Prime in Silver, in Car mode! I think he looks slick; ROTF Leader Prime, Universe Cyclonus

Worst - End of Animated, the endless bagging out of ROTF - why are so many people too critical of it??? I was satsified with it. Also looks like many millions of people were as well. Plus it maintained TF awareness into mainstream society. Well that is my opinion anyway.
