Not only will you miss out on the visual grandeur of Jackson’s trilogy, but you might also go insane. Definitely don’t watch on a phone or tablet. Watch on the biggest screen you have access to. Not everyone has an enormous TV, but you should try to watch on the best screen available.You’re already committing a day to the trilogy, so you might as well do it right. The extended editions add a number of important scenes that weren’t in the theatrical cuts, especially The Return of the King (The Mouth of Sauron, The Houses of Healing, etc.). Together, they’ll add two hours to your binging day, but it’s worth it. Buy the extended editions (or figure out if they’re available to stream in your country).
