Critics are people too, they can like or dislike a movie based entirely on their misunderstanding of the movie. Having comedic elements doesn’t make it a comedy, lots of different genres touch on comedy to break up the emotional weight of the story, and to set up the audience for a bigger hit.
One can say that a lot of Depalma’s “thrillers” border on comic. Carrie, Phantom of the Paradise, Dressed to Kill. You can’t tell someone what they did or didn’t find funny.
