G1 Transformers was horrible. Watched a random episode the other day, when confronted with proof that the Decepticons were doing dirt, he told Cosmo that it doesn't mean they are doing anything. No wonder Cosmo stayed in space, I would too.
My favorite part of G1 Transformers any time I decide to watch an episode is Starscream standing right in Megatron's face telling him he ain't shit and how he plans to betray him. And that Megatron is apparently cool with this blatant insubordination because he just continues on business as usual. I don't know why, but that dynamic is highly amusing to me.
