I really wanted to like ITV's adaptation of Wuthering Heights, but it was pants. I have no idea what was going on at the end and I have read the book. Unless it was mentioned in the first five minutes which I missed, nothing was said of what happened to Isabella, who presumably died; Heathcliff seemed to be auditioning for the part of Snape in Harry Potter and was not at all sexy (in fact if he had been Snape in Harry Potter, or at least Alan Rickman's version, he would have been sexier); no-one appeared to age at all apart from in a big leap from child to adult (couldn't they at least have greyed Heathcliff's hair?) .
Worst of all I thought there was absolutely zero chemistry between Cathy and Heathcliff. When they said "my love" it sounded like they were saying "cup of tea" or "bus-stop". Despite snogging the faces off each other I just wasn't feeling the spark, and that's what the whole book is about. Without it Cathy is just a spoilt child and Heathcliff is a brute, and that's about what they were.
I want to re-read the book now, though.
