Stephen King is not a good writer. He has great story ideas; but, his actual writing is poor and he does weird things that are unsupported by the narrative - like writing sewer gangbang scenes with children so that they can defeat the bad guy with the power of underage eskimo brotherhood.
You can explain that in a less derisive way that sounds a bit more reasonable, but it doesn't make it a good narrative choice.
Another example is 11/22/63. People on reddit cream their pants over the book, but it's literally just King self-inserting as the main character so he can (totally uncritically) reminisce over how great small town America was in the 50s/60s and have a fantasy relationship with this incredibly weak/badly-written female character and repeatedly "make poundcake" with her and drink rootbeer floats in diners or whatever. It's an 800+ page book (paperback is 1049 pages) supposedly about time traveling to stop the Kennedy assassination (which is a cool story idea), but like 700+ pages are filled with asinine garbage and the actual plot is thin and pretty bad.
