"One that treats the source material with respect"??? HA!!! The source material is a bunch of toys. Kids don't respect the 'source material' - they bash the hell out of them till they break.
And if it's a specific continuity you're talking about...well, pick one. And I don't mean one of the newer shows - I mean G1 cartoon, G1 U.S. comic, G1 U.K. comic, Dreamwave G1, IDW G1, Devil's Due JOE/TF G1, Alternators, Classics, etc. G1 is itself its own multiverse, fractured and irreconcilable to most who seem to think it was end-all-be-all of TF series.
I love G1 more than any of the other series, but I admit Beast Wars was better. We got good guys who made mistakes and a Megatron who actually accomplished something.
Besides, we've got enough damned remakes as it is.
