I bought it from Apple. Same price as two tickets at my cinema and much better quality than the compressed shite the likes of yify serve up. Main reason was it meant I could watch it with subs.
Overall, a brilliant film albeit not as good as part 1, which is the opposite of my experience reading the book - the last 3-400 pages are superb. A lot of departures from the book, which is totally fine as I’d wondered how they could faithfully show the passing of time. The most jarring change was Chani’s character and role, though Zendaya played it well nonetheless.
Hope to see more sci-fi and fantasy from villeneuve. He’s a master of it!
