I see what you're getting at, but in ME3 we never have any meaningful interaction with him. He just shoots Shepard with his giant energy weapon, and that's about it. He's not really a character in ME3, just a force. In ME2, while you never get to have a conversation with him, he at least hams it up on the battlefield whenever he's present, and you get a sense on Horizon and especially the Collector ship of an intelligent opponent who is trying to do in Shepard personally, as opposed to ME3 where the Reapers were more of a faceless juggernaut smashing their way through the galaxy.
