They're super lovable - I enjoy the constant callbacks in the sequels, and the situational developments for all the characters over the series (including minor ones), and Joyce's wry unreliable first-person chapters.

Roll with the confusion. As readers we're being aligned with newcomer Lockwood (who admittedly is a fool), and thus deliberately being invited to also try and sort out the confusing muddle of intwined Earnshaw/Linton relationships (hopefully more successfully than him)...

It's a low-key mystery element to the narrative. Embrace it!
