Winchester Brothers: Supernatural was a bit of a breakthrough after Buffy, the Vampire Slayer, in terms of being a TV series that was dedicated to monster hunting and extermination. Add some ghouls, fallen angels, zombies, and other out-of-this-world predators, and Supernatural addressed all of them with the duo of the Winchester brothers kicking some serious ass. Bhoot Police surely borrowed this idea, but the chemistry between Arjun Kapoor and Saif was just not the same. I cannot call this a lame attempt since it was done decently but it just did not make an impact.
The Grudge: Hollywood remake of the Japanese horror icon laid new standards for presenting the creepy type of horror, moving away from the horror genre that was typically high on special effects. One thing that every first-time Grudge watcher would remember is the body-twisting and bone-cracking sounds. Bhoot Police borrowed the same, on two occasions, if I remember correctly. The impact again was missing. It was done a bit too quickly and without any creepiness being created.
