Of course not. Most people don't re-read books they were made to read at school; especially when they made an imperceptive comment such as "Wow, Heathcliff is wicked cool" (having come to about the fourth page) and the teacher slapped them down for imperceptiveness.

I would add to your comments about unreliable narrator types, that Lockwood himself is set up practically from the start as a posturig prat, and that one of the points made by the story is the distance between his bookish Byronizing and the real fury and horror of Heathcliff. Certainly bitter irony is not a minor part of this dreadful romance (I use the word in its literary, not its sentimental meaning) by the angry, atheistic daughter of a brutal churchman; even the conventionally consoling mention of "tranquillity" in the close does nothing but underline how little Lockwood has really understood.

I would take you on on racism and such, but what's the point?
