I really enjoyed Betaal, it's high time we start producing quality Indian horror which is not cringy to watch. My favorite aspect about Betaal was that it brought zombies to an Indian show for the first time but was also able to tie it very naturally to Indian mythology. If you're familiar with the Vikram and Betaal stories you'll be able to notice the subtle but skillful way they wove it into the plot. At just 4 episodes, I thought it was just enough so it doesn't end up being too draggy. Definitely worth a watch!
