A lot of superheroes died in Avengers: Infinity War.
Some died more permanently than others.
Heroes that died include Doctor Strange, Spider-Man, and Groot.
Marvel Movie maniacs know that most of these deaths are just temporary.
Avenger 4 will bring most of the heroes back to life.
But, fans are meant to believe that the deaths are real.
Kevin Smith, a Marvel comics super fan, isn't buying one of the deaths.
