This is a toughie. There are many reasons why this book is so notorious, but I'll stick with two reasons. The first is that the bulk of this book is people reacting to the admittedly awesome cleanse of saidin at the end of 'Winter's Heart'. It was awesome, but did we really have to read through all of those reactions, we easily could have just jumped right to people's responses to the phenomenon.
The second reason is Elayne and Aviendha taking a bath together. There's nothing salacious there, and we had plenty of Egwene and the Wise Ones sweating together in the lodges back in 'The Shadow Rising', but it was such a long bath. So very, very long.
'Crossroads' spends a lot of time reeling out some of the back storylines, without a whole lot happening. The bath is just too good of an example to pass by. Elayne and Aviendha are successioning in Andor, and we learn that claiming the throne of Andor, and carrying babies, can be deadly serious business.
Perrin is still chasing after Faile, who is still a prisoner of the Shaido along with Morgase, Alliandre, two others and two Aiel. Masema is...around.
Mat is playing getting to know you with his suspected bride along with Egeanin, Domon, and once-prominent characters Julien, Thom, etc.
Egwene's politicking with the Aes Sedai is more showing us the steps characters must take to grow, but it sure isn't exciting. I chaired the main administrative body of my municipality (sounds exciting right?) for two years, and sat through many meetings that mimicked the meetings of the Hall of the Tower. Jordan nailed it. It was like I was there! As dull as those scenes could be, I had to grant points for accuracy.
Rand... shows up! He does orchestrate important things, and we get to see Loial again (yay!), but there's not a whole lot of movement.
After 'Crossroads' came out there was a longer wait than usual for the sequel, as Jordan chose to flesh out a prequel story called 'New Spring'. I was too disgusted to read it at the time, but I'll get to it this reread, eventually.
