I love G1, I have never been able to get into any of the other series'.
I love the dynamic between certain characters: Megatron and Starscream for example.
Optimus Prime is THE greatest machine ever.
While I am willing to go and see the movie, I am disappointed that the robots lack so much personality and charm
Also with actors like: Cullen, Welker, Latta, Sue Blu (who later worked on Visionaries) etc the show was amazing.
