To date, the only superhero franchise to fully embrace the R rating is Deadpool, though raunchy adult humor is the envelope those films push, not horror tropes.
Obviously, IT’s R rating didn’t deter fans or critics, nor did it limit the property’s potential for a sequel.
The site states that an R rated Venom is now extremely unlikely, despite trailers for the film featuring more extreme horror elements than your typical superhero fare.
I’m still willing to give a PG-13 Venom a whirl when the film invades US theaters this fall; I just won’t go in with the same high expectations.
