What the hell is supposed to be so impressive about the last one by comparison to all the rest(except of course the Adam West one)? Ellis gives no reason he should inspire such awe in Jakita and Elijah when none of the others do. Ohh, shiny spiffy!
I think it's more the combination of Batmans than just the last one. They earn respect for all of the Batmans, but only show it for the final one because he's the only one being cooperative.
