Maybe because books and movies are more static/unchanging in nature? I realize IMDB also does TV but even then many podcasts have a frequent release schedule that outpaces nearly every other medium besides maybe streaming. Because of this, reviews become stale quicker, and some podcasts talk about something different every episode which makes recommendations trickier
Also worth noting Amazon owns both IMDB and Goodreads. Many folks seem to think they're neglected now and not great platforms anymore
