My very random thoughts include:

Why is this called The Old Curiosity Shop when said shop is abandoned so early in the story?

Can a pony legitimately be my favorite character? I laughed out loud every time Whiskers and his antics were mentioned. No? Ok. Kip, then. Certainly not grandfather...or even angelic Nell.

Anton Lesser's narration is magnificent. I can't imagine the time he must have spent getting the various characters down and just how to deliver each piece of dialogue. He particularly conveyed Samson Brass well.
