In the original cartoon & comics, Unicron isn't really "dead", infact, Starscream even made a deal with him in one of the ep's to give him a new body. And Primus is the god of the TF's in the original comics(not the cartoon though), The Fallen, is in the newer comics, adding to the original's mythology. But that's all G1, the movie ain't G1, that's for sure, but I still find them interesting. I'm not thrilled with the designs, but, I've learned to accept them. I'm hoping the designs for new characters in the 2nd film, will lean more towards a more traditional TF look. This is the best we'll ever get, I don't see anyway we'll get TF's the way we want them, so I just put up with certain things I don't like, but, this new movie will be focusing more on TF's mythology, not to mention, supposedly having more focus on the TF's themselves, & less on their interaction with humans(which is one of the things that bugged me about the 1st movie, TOO MANY HUMANS!).
