This is the reason why Spider-Man was treated differently in Avengers: Infinity War

This may be a good time to discuss some scenes of 'Avengers: Infinity War', especially those that left the fans heartbroken. We are referring to half of the Avengers' world being reduced to dust. If you've not seen the film yet, this is a spoiler of sorts as we are discussing one particular superhero's death being treated differently - and that is of Peter Parker/Spider-Man.
His death was given a different treatment - a long one,, where As Peter Parker/Spider-Man tells Tony Stark/Iron Man that he is not feeling so good. “I don’t feel so good," he tells him, adding, "I don’t know what’s happening. I don’t want to go. I don’t want to go, Mr. Stark, please.” The scene tugged at the heartstrings and was highly praised by fans.
The film’s directors, Anthony and Joe Russo, confirmed the theory, saying that it was this superhero's spider sense (an alert system that warns the superhero of danger) with its heightened sensitivity which makes us aware that Thanos’ is going wipe away half the population of universe. This trait is seen in the scene where the hair on on his arms stand up at the arrival of the Black Order’s ship.
