does anyone else think Barry keoghan playing duke just don’t seem right ?

He is a very good actor I’ve enjoyed a lot of his films and shows and I am a fan of him but there’s just something about this that dosent feel right , Conrad khan who played original duke did it way better he actually suited every scene he was in , he just seemed like the natural fit but Barry playing duke dosent somehow ? I think they should of left duke out of it if Conrad wasn’t playing him what does everyone else think
