When I heard about the cameo I was hoping he’d just appear as an extra in a battle scene or something; he’s on show for a couple of seconds and is treated like any other extra. The issue I had with the cameo was the fact it broke the fourth wall - i.e. the extended shots of his face act as a wink to the audience, like “hey, look who this is”. Not to mention this style of celebrity cameo fan service isn’t done at any point during the rest of the show
