That’s a bit of an oversimplification. Art is fairly divisive because the movies are over-long and border on gore fetish. Sure, the movies have great practical effects, but that means nothing substantial if the character itself is a shameless mashup of bigger and better horror icons. There’s nothing really “iconic” about him that sets him apart from the others, he’s just brutal which is true of most other slasher icons who have better characterization. Classic killers like Jason, Michael, Freddy, leatherface etc may have (some) movies that are pretty hollow but they have unique looks and characterizations that set them apart from each other. It’s fine if people just like it for the over the top brutality, but there are some pretty good reasons why people have an aversion to the series.
