Gore films are the couch potato version of ' aaj kuch toofani karte hain!'

This bloody (literally) genre inflicts viewers with graphic visuals. Guts are spilled, eye balls are spliced out with surgical knives, the human anatomy is split wide open to give us a closer look at the organs in our body. However, these also have a cult following and include some of the best stuff you can watch with your friends on night-outs.

Here's a list of 25 gut-wrenching films, which make you question as to how much is too much?

1. Requiem for a Dream (USA), 2000

Not much for blood or gore, but this is one harrowing movie about a couple of drug-peddlers, a sex worker and an elderly woman hell-bent on losing weight via 'diet pills'. Deeply depressing.
