Being somewhat (!) obsessed with the novel, I've watched every adaption of it going and this is undoubtedly my favourite. It fully captures the darkness and moodiness of the novel and the almost painful love between Cathy and Heathcliff.
Tom Hardy and Charlotte Riley have incredible chemistry in their roles, which isn't surprising since they were falling for each other in real life (and unlike Cathy and Heathcliff, they are still together, yay!). Their emotion and passion for each other really comes through, and it makes their complicated love story so much more believable. We can truly see how they are better together, terrible apart.
Aside from the leads, the supporting cast are excellent - particularly Nelly, Edgar, and Hindley. The scenery is spectacular, showing the beautiful wild of the moors. The script is a much condensed but fairly faithful version of the novel. In short, I loved this adaptation the minute I watched it and having watched it 11 years after its release, I loved it just as much.
