I finally finished reading and studying it the other week! It's now one of my favourite books although I initially found it difficult to get into, but having read it once and looked over the beginning again, it's so much clearer and compelling.
SPOILERS!!
One thing I will say is that I despise Heathcliff, a lot of people in my class defended him regardless of what he did, he could become a serial killer and a lot of them would condone it or justify it. 18 years, for a start, is far too long to obsess over somebody and then he has necrophiliac urges which was pretty repulsive
But his treatment of Nelly was disgusting, his behaviour towards his son was appalling (although Linton was also one of the most disgusting characters I've ever come across as well) and then beating up Cathy 2 on several occasions was the final straw (I utterly adored her). He might have been a victim of circumstance, but he's a grown adult at this point and he's just repulsive in every way.
I also didn't like the original Cathy either... at all, so Heathcliff and Cathy's romance was of little interest to me whatsoever, although the storyline is extremely short which I was quite shocked by considering how iconic the two of them now are. But I adored Hareton and Cathy, and so I loved their developing relationship and the ending was nothing short of terrific to me.
But all of the characters were developed to such a point that's it sad to look at them as just characters if that makes sense, they're just so lifelike and reflective of reality. Isabella was another favourite of mine even though she had many flaws, I did like how she stood up against Heathcliff and left him, although he tried to kill her so she had no other option I suppose
but as a young woman, with no relatives since her brother disowned her in addition to possessing very few legal rights in her society, I loved her decision to flee despite the odds being so heavily weighed against her.
And the violence, too! There were quite a few physical fights between more or less everyone at some stage, but it worked well, and it was a nice surprise to find in what I thought was going to be a stale book in those regards.
But yeah, I'm thrilled my sixth form chose to study this book, it'll stay with me forever!
