These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Adaptation Distillation: Does a good job adapting the original storyline, streamlining the cast and dropping the annoying friend characters who exist mainly to die in the final act of the film. It also tosses in the bit of fan service of having the main character be called Axel, who many fans of the original film liked prior to the reveal that he was the killer better than the Designated Hero TJ.
Hilarious in Hindsight: They switched the names of the characters for the remake in terms of Axel the good guy and TJ, now called Tom, the bad guy.
Complete Monster: Harry Warden, in a case of Adaptational Villainy. In the original, he only went after the two admittedly negligent supervisors, with the excuse that he had been driven insane by being forced to eat the corpses of his companions who had died in the cave-in. In the remake however, he is shown to be a cruel and condescending bully who personally kills his fellow trapped miners in order to steal their oxygen supplies. He then slaughters nearly two dozen innocent people (most of them invalid hospital patients and children, according to a newscast) because... he was really pissed off.
Crosses the Line Twice: The killer murders a little person by impaling her to the ceiling with what was essentially a golf swing.
Narm: Ben's death actually was pretty frightening, up until the blurted out "Shit!"
The killer getting whacked with a piece of frozen meat, even though it was probably supposed to be comedic.
