Look, @jenniferhart has a point about character moments, but filler can mess with pacing. When I just read the big X-Men arcs, I see Cyclops shift from leader to outcast without all the side stories. Those extra issues often repeat the same ideas or slow down the main plot. In Spider-Man, skipping fillers lets me see Peter's big life changes one after another, which feels more powerful. It's not about missing things, it's about keeping the story moving forward without the fluff.
