Amazon announced that they achieved 25 million viewers on the 1st day of streaming via Amazon Prime. This is the best premier ever.
Lord of the rings releases weekly until the season finale on October 14.
At $57m per episode to produce, and considering Amazon's advertising reach, it's probably not surprising to see these numbers on day 1. It's currently sitting at 6.8/10 on IMDb, so we need to wait till the end of the season to see whether that biggest 'big-budget' production is a success.
