I'm having a hard time choosing a rating for this book. I'm certainly glad i read it, since it's such a classic. But I think i was bored enough at times to miss important plot elements somehow. I'm still not really sure how the eff the ending happened the way it did. I'm not really interested in geology, so all of the geological details were dull to me. And i thought it was a little too convenient that the narrator happened to pass out any time something important was about to happen. How does Jules Verne explain how the explorers got from point A to point B? Sometimes he simply doesn't. So the journey was rather hard to follow. 
 I wonder if i just read a bad translation or something. The verb tenses seemed to jump around madly sometimes. And i spotted once or twice a phrase that would've made more sense in French, leading me to believe that the translation was at times too literal. 
 I did love the parts where they were discovering wonderful things in the underground world. Enormous flora and fauna and crazy natural phenomena--i love that kind of stuff. And parts of the story were genuinely gripping. So i'm going with "i liked it." Even though some things about it irritated me.
