Maybe it was just the version I saw but the entire film was just so dark and twisted and awful. Heathcliff is, from his childhood, possessive and obsessed with Catherine, whose father adopted him as a child. Catherine is torn throughout the film and then becomes just as vindictive and obsessed. They live dark and dreadful lives. Heathcliff does all he can to ruin the lives of everyone around him. This awfulness goes on throughout the film until the last 4 minutes, where the next generation begin to fall in (real) love and Heathcliff dies. In death Heathcliff is reunited with Catherine.
It's totally messed up. They lived awful lives to the end and then suddenly they're all happy and skipping and everything is wonderful. The end was certainly a relief from the horribleness thus far, but it definitely did not remove the negative feeling I got from it. **Shudder**
I think I need to go and find some EFY music!
