you know what, i was extremely similar. i haven't listened to love supreme in a long time, but i got that CD as a birthday gift about 2 years ago. i popped it in and i hated it. absolutely did not understand why people thought it was so great. over the next 2 years, whenever i hear people talk about how great coltrane was, i think "why." i then got his giant steps CD for a christmas gift this year, and oh my word. completely different than what i was expecting. i couldn't stop listening to it. giant steps, countdown, Mr PC, i love em all.
sorry i can't answer your question. ive been wondering the same thing myself. although i need to find love supreme and give it another listen before i make final judgments on this
