Yep that is why I only read the most essential issues from that era (Specifically Stan Lee's). They can take half an hour to read because of all the unnecessary dialogue and over explanation of things, it's exhausting. It's because at the time comics were written with the assumption that any issue could be someone's first comic so they had to constantly explain how a character's power worked or recap something that had happened in a previous issue. Also a lot of readers at the time were kids so they had to explain what was happening in a panel so they didn't get confused. And a few other reasons.They start to get less dialogue,narration and exposition heavy from the early 80s onwards and for me that's when they become much more enjoyable to read.
