Conversely, I see Anthony getting criticized a lot for his work (particularly the sexuality between older men and prepubescent girls that pops up in more than one book). More over at RPGnet than here, mind, but I can certainly say that I've seen people discuss Anthony's work with even more disapproval than Greenwood's.
The problem with Greenwood's novels is not the sex between old guys and hot young women. The problem with the novels is that for some reason, while Greenwood is excellent when he is writing RPG books he is just poor at writing novels. Bad plot, bad characters, too much forced awesome trying to make up for the former.
