Spoiler A) Surprise only lasts so long. Given the number of assailants and the time he took chatting with them, any surprise had been well and truly negated. B) We saw no planning, so that's nothing more than assumption on your part. C) Are the other Predacons totally without this apparent training? D) Without taking a single blaster shot. It's all very unrealistic. And let us not forget: this is Transformers! The brand of Optimus Prime, with a torso blown half to hell, rising to defeat Megatron. Of the robotic gore of the G2 comics. Of Optimus Prime, with an arm blown off, welding a mighty axe. Of Dinobot himself, sacrificing his mind, body and Spark to save the human race (and reality itself) by taking on the entire Predacon force. Show me the damage. Show me the risk. Show the stakes. Walking away from a fight without a scratch isn't my idea of entertaining.
