I'm about 40 chapters (~350 pages) through. I wouldn't say it gets better, or worse: I loved it from the beginning. If you aren't hooked by 100 pages, I'd put it down. However I'd recommend coming back to it later, maybe in a few years, try it again, see if you don't get more out of it.

Also, if you didn't read the Edith Grossman translation, try that, it is very smart and modern. The older translation feels a bit stuffy to me.
