I dunno I like the spikey way Danny Miller plays Aaron. It's actually representative of that quota of almost still semi-closeted guys whose gayness doesn't sit easily with them. Not everyone is comfortable in their own skin or can deal with society's reactions toward them.
I don't mind Aaron's dour darkness, why should gay men be all intellectual nerds or happy jazz hands types? At least Emmerdale has addressed that people from all walks of life and personalities can be gay.
And if Miller was so uncomfortable in the role would he really have come back? I've seen him in other roles and to my eyes his grittiness is just a part of his personality.
I admit I did kind of smile as they had a big grimey punchup in the 'dale garage yard over a boy. It was gold.
