Well, let me be clear: I like not love Hogarth. I love his voice, I think he's an AMAZING front man, but I find him tiresome at times, and preachy. I don't need Marillion to be "prog" - some of their best work isn't - but I do need them to be... vulnerable, for lack of a better word. At times Hogarth can be a shade too sanctimonious, and a shade too ready to be different just for the sake of being different. That was Holidays for me. I love Brave, and, even though it took me a while I love Afraid of Sunlight too, but This Strange Engine turned me off to Marillion until Marbles (ironic, because TSE is supposed to be Hogarth's most personal work up to that time).
It's weird, too, because Fish can be sanctimonious too at times (Brother 52, The Perception Of Johnny Punter) but it's offset by his willingness to be naked (the title track to Sunsets On Empire is just BRUTAL). I don't get that same level of introspection from Hogarth (except on the excellent Marbles).
