I think it is one of the most beautiful places in Skyrim, yet its one of the most boring and confusing. The colors and ethereal beauty in Blackreach is spectacular. Also the fact that it is a giant Dwemer city in the underbelly of Skyrim is mindblowing. Yet walking around there for hours is dull and you feel like you've just been walking in circles. I literally just finished the Crimson Ninroot quest and I've had the game since it came out. I've been trying to avoid that quest for ages, but I wanted to get it off my unfinished quest list because I was sick of seeing it
