Unlike most reviewers, I preferred SEIGE - and the eps on Cybertron were certainly more interesting than on the Ark.
Don't really mind that OP and Megs talk so slowly, but they had a lot of repetitive interactions that didn't really progress things, and there was a lot of aimless time in space (the Scorponok battle went for sooo long - why?). Ep 5 was super wacky - wayyyy too much exposition + I didn't understand where Unicron and Galvatron fit into the timeline thing... but keen for a new toy of him regardless :P
