The dialog is pretty consistent and certainly gets overwhelming at times. I understand why Erikson started the story where he did but you're dropped into the story about 100,000 years after it started. I'm 16 books in and just starting to understand the events that kicked everything off.
All that said, best books I've ever read without question. %100 with the read. If you want another entry point I might suggest giving Midnight Tides a try. It is the 5th book and takes place on the other side of the world with completely new characters so you don't need any context from the first 4 books. Midnight Tides also contains my 2 favorite characters in all of fiction, the banter between Tehol and Bugg is immaculate. That dialog is probably a better intro than Krul and Krupe.
Did a road trip in a friend's Model 3 with FSD and it is significantly more stressful than my VW or my wife's Acura driver assist features. It made a staggering number of minor mistakes including hallucinating pedestrians for every semi that was more than a mile ahead. It would slam on the brakes when this happened so you had to watch it like a hawk for every hill crest. The other really nasty one was sudden, violent lane changes. Especially if you were in the left lane with someone behind you.
I have gotten to the point where I wonder at people who say they love FSD. My experiences with it are so overwhelmingly negative that I have to assume there is something different about the roads I drive on compared to what it is trained on.
