I'm 52% in now, according to my kindle.
I think I like Dickens best when he's being comical—or David best when he's being ironical, such as when recalling how ridiculously he acts when in love with Dora ("I turn hot when I remember the cravat I bought. My boots might be placed in any collection of instruments of torture.")
I like him less when he's being tragical, when he has a tendency to become a bit sentimental and hokey, straining for effect. At such times as Barkis's deathbed scene, which don't get me wrong has its virtues, you can see how hard he's TRYING to be moving, that it can be hard to be moved.
I am detecting, at this point, a theme (the 'bildungsroman' theme) of David learning to distrust his first impressions of people. I mean it's obvious—Steerforth turns out to be some sort of villain and Miss Mowcher the comic dwarf turns out to be sensitive
"‘What can I do?’ returned the little woman, standing up, and holding out her arms to show herself. ‘See! What I am, my father was; and my sister is; and my brother is. I have worked for sister and brother these many years—hard, Mr. Copperfield—all day. I must live. I do no harm. If there are people so unreflecting or so cruel, as to make a jest of me, what is left for me to do but to make a jest of myself, them, and everything? If I do so, for the time, whose fault is that? Mine?’"
Anywayyyy, it's hard to believe I'm only halfway in at this point but I am still enjoying it—and when he is being comical, REALLY enjoying it.
