Watched the first 3 episodes of Interview with the Vampire. Minor spoilers for this, the 1976 book and the 1990s films may follow, but nothing major.
Overall it's been highly watchable so far. The production value is gorgeous, like an HBO show--- does an even better job of recreating 1910s (yeah, more on that below) New Orleans than even The Gilded Age did with NYC. Special effects are used sparingly but generally look great. The story is engaging, but again, more on that below.
I don't recognize either lead, but both are great onscreen. This is the best live-action Lestat. He perfectly captures the character from the first book, the mix of magnetic charisma and petulance. He also sounds convincingly French.
Louis is played by an actor with amazing screen presence, He owns every scene he's in. Here's the thing -- this isn't the previously established Louis. Rather than a 1700s white plantation owner, this is a 1910s black businessman, with siblings I believe added to the story (they certainly didn't make as much of a mark in the book if they're there). He has a forceful personality, unlike book Louis, showing agency before and after meeting Lestat. He's a better, more interesting character than book Louis in every way. But until the final minute of episode 3, this may as well have been a retconned mid-quel--"oh yeah, btw Lestat woke up for a while and returned to NOLA in the early 20th century, he just never talked about it"--as the lead character and his arc are so different. It looks like this may track more closely with the book going forward, which is a shame, this somewhat new tale was a refreshing addition to the Anne Rice universe.
