Which Megatron, though? Gun? Tank? T-Rex? Mechanical T-Rex? Dragon? Robot Dragon? Any of the crap, crap, crap "new" TF designs from Cybertron/Energon/etc.? How are those "related"?
Face it, the G1 designs were retired LONG before this movie was even announced. When this movie comes out, I'm going to see it with a blank slate in my mind. This is a complete re-telling of the TF story, from the ground up and I'm going to treat it like that.
The G1 designs will always have a nostalgic place in my heart, but they're hardly the OMG TEH ONLY AWSOME! that most people ascribe to them.
Do you also hate the the VF-11, YF-19, YF-21? Those have almost nothing to do with the VF-1, so do they deserve the same amount of vitrol directed to them?
