Is 'Venom' the darkest Marvel movie ever?

In the two trailers we have seen for 'Venom', the titular character has threatened to eat a character twice and apparently followed through with the threat in one of those occasions. In the world of Loki’s playful antics and Star Lord’s cheesy one-liners, Venom stands out with its darkness and gritty violence. The film’s director Ruben Fleischer claims that 'Venom' is Marvel’s first dark film, where violence will be ‘pushed to the hilt’.
This tone is reminiscent of the comics, where Venom was always darker and more visceral than other superheores and even villains. The film’s lead actor Tom Hardy believes the makers have kept that dark essence from the comics alive in the film too. At a press conference in Moscow, Hardy said, “The depiction of Venom, I think, has been extremely faithful to the comics. If we look at some of the images directly from comic book, they haven’t deviated in any. If anything, they’ve recreated certain elements accurately from the comic books.” In fact, one of the character’s lines from the trailer that is going viral these days: “So many snacks, so little time!” has been lifted directly from the comics (Venom says this while fighting Spider-Man in 'The Amazing Spider-Man' (Vol. 1) #374).

Other Marvel films have come close to touch this level of darkness before, most notable being the Deadpool franchise. While Deadpool packaged a whole lot of gore and profanities into a 1 hour 49 minute journey, much of its darkness was offset by how zany and meta the whole film was. It’s hard to ponder about darkness when the protagonist is making jokes about genitalia and breaking the fourth wall every seven seconds. In 'Venom', however, the lighter moments are used mostly as clutter-breakers, and not something that defines the film’s tone. In an interview to a comic book portal, director Ruben Fleischer said, “Our movie wants to honour the comics as close as we can tonally. In the comics, he bites people’s heads off and eats brains. It would be weird to make a movie with Venom if he wasn’t doing that. We tried to honour it as closely as possible. This is definitely a darker, more violent, more vicious Marvel character than I think anyone’s ever seen before.”
However, the film’s PG-13 rating has left many wondering if it will go a little soft on the gore and violence, and how it will compare to superhero films such as 'Logan' and 'Deadpool', both of which were rated-R. Industry sources say that the film is indeed dark but the gore has been toned down to get the PG-13 rating as this leaves the option of having Spider-Man face off with Venom in the sequels. Marvel Cinematic Universe (where Spider-Man currently resides) characters generally do not appear in R-rated films as they cater to niche audiences.
