I've never actually picked up an Arthur Conan Doyle story before, but this one—with its adventure-heavy focus and occasional dinosaur—is so up my alley that it seemed like a great place to start. And it was! As dated as this is (and believe me, it's dated), I'm surprised by how much fun I had with it. I can't say it's a riveting story, as the pace and general plotting prioritize steady build-ups over thrills. But there are the occasional thrills, and the sense of discovery, while muted than our modern expectations would lead us to expect, still carries enough genuine excitement to make the journey worth taking. Professor Challenger is a fantastically hatable character, too, and is so far up his own ass that his unceasing arrogance becomes a farcical delight instead of a total annoyance. He feels like the antithesis of Sherlock Holmes, with his burly physique and fiery temper giving his untapped ego and intellect a wholly different vibe than the one Holmes is famous for. He's definitely a character I loved to hate and hated to love. 

The characters are a mixed bag overall, but the core adventurers have enough variety in their quirks that I never disliked anyone (well, not more than intended, anyway). It's too bad the POV character is the weakest link, as his empty personality and iffy-at-best opinion of women tested my patience more than once. There are other areas of friction, though, as the book is a relic of the era and, as can be expected, is littered with unsubtle racism, sexism, and a general air of Western Exceptionalism that's so pervasive it feels almost parodic. I knew to expect all that going in and had my guard up and ready for those less-than-pleasant aspects, which helped me power through to get to the parts I liked. I can't say it's a book I can heartily recommend, but I enjoyed my time with it (although I wish my audiobook had a better narrator) and am glad I took the time to give it a go.
