If you go to forum.candlekeep.com and ask the same question you should be able to spawn a 20-page thread of bile and vitriol directed at the 4E Realms. Personally, I enjoy it. The only thing I dislike is that the map is the worst map in the history of RPGs. Even its colour palette was determined by the contents of a baby's diaper (I'm not joking: it's a mixture of greens that I saw in my son's diaper when he was around 6 months old). But most of the hate is focussed on the destruction of what was there before (which I personally like: more plot hooks for me!) including dead deities (again, more plot hooks!).Any reason it's regarded as so unpopular? I'm just getting into post 4e Faerun and this makes me a little curious, as the Realms have always been one of my favorite settings.
