I don't think anyone is denying the likeness, or saying that it doesnt look like Cavill.
My opinion is, quite simply, this isn't a particularly exciting looking figure, nice by all means, good even - but I dont have that same level of "HOLY CARP!" excitement as I did for the rooted Aragorn, Harry Potter, Joker, Gandalf, Pennywise and Batman - I dont feel the urge to obsessively look at the pictures and feel my excitement grow the longer I look at it, this is just a nice figure I can appreciate - it doesn't light that insane collector urge we all know and share.
In that respect its more like their Bruce Wayne and what I've seen of their Paul Atreides so far - really nice figures, but not blowing me away.
