It's not easy to say this book deserves one or three stars: it's just too old for it. It's value resides in that it's one of the earliest novels in the English language and the genre itself was just finding its footing.
The storyline itself is really funny and interesting but I found the style too removed of what I usually like: there's lots of telling and too little showing.
I believe that, for modern readers, this book is interesting for it's meta value: the short essays Fielding inserted before each part, the story-within-a-story that was so common in novels at the time, the sheer novelty of the book itself.
If you are not interested in how books and novels change through history, I'd stay away because there are too many things that a modern reader might find foreign.
