I had seen this interview of Vikram where he said that the graphics and VFX are a strong point of the show, which it indeed is. And it's a challenge to act without graphics in real time.
How difficult it must be to act when there is nothing in front of you. For example all scenes with Baazigar, in the forest, with the book, etc etc. Never have I felt that their expressions weren't on point or Bazigar doesn't exist in the real frame of the scene. Even when they look at a particular thing (which must be staring into nothing), it's so seamlessly blended later that we don't feel it ain't there.
Hats off to the cast and crew!
And also, I'm loving the direction these days.
Keep it up!
