Will Ladislaw's character depiction

Henry James did not think the character of Ladislaw was very well depicted. I am reading some student notes which mentioned the review. What did you think? I thought he was all right. To me he seemed like an artistic version of Lydgate, although less cagey. Maybe he had too many talents heaped on him, and had too exotic a background to be very credible. I have to say, I thought his German art student friend was very well described. He was witty and different. Perhaps Ladislaw was not as well depicted as him.
