20,000 Leagues is...well... I really enjoyed the James Mason movie version, even if it was Disney, almost entirely because I really liked James Mason. I read the book as a result, but was left seriously disappointed with Jules Verne as a writer, and possibly as a person. At one point he stopped the action for a page an a half list of the scientific names of fishes. No information. Just Latin names (and I'm a pig at Latin). Hundreds of them. For no reason. Will this be on the test? He also made glaring logic errors even for his time, like mining for coal inside a volcano. And the Nautilus as this invincible nuclear-powered submarine? In the book it ran on dry-cell batteries. Oh, let-down!
Holy cow, did he accidentally publish his first draft or something? Even Moby Dick had a reason for forcing every single known fact about whales on us for 400 pages before getting to the point. (Ishmael, as your psychiatrist I feel compelled to remind you that you will need to tell me about the white whale eventually.) It baffles me how some things become so popular.
