Good luck with that. Even with those, we'll never know the real numbers because only Amazon has that. At this point, if Amazon did release numbers I don't think I'd believe them. We've already seen them play this game when saying they had X amount of viewers, but the fine print is that a viewer counted as someone who watched only a few minutes (not even the full episode)... for all we know half of those people turned off the episode 10 minutes in and never came back. There's been insider reports for a long while that regardless if RoP does well or flops, Amazon will publicly take the stance that it's the best TV content ever, however I wouldn't doubt if we start seeing some quiet action and changes taking place in the months following the finale.
Regardless, normies drive those kinds of numbers, and I have a sneaking suspicion there will be a large drop-off in RoP normie viewership around episode 3 and episode 5/6. I chose these spots because RoP is extremely boring for the first couple of episodes so you'll just lose people who won't return at around the 3rd episode, and around 5/6 the writing and plot take such a large nose-dive that even normies have started to say the show is dumb. Considering the high praise I see from some individuals about the finale of She-Hulk, I can safely assume that there will always be an audience for shows regardless of how trash they are... the question is what is the floor viewership for RoP?
Ultimately, I don't think RoP is going to have a lasting positive impact on people. If you talk about PJ's LotR trilogy, that's had an insanely large impact on people that has lasted two decades and still has people who enjoy watching it and sing its praises... because it was actually good content regardless if some of the lore aspects were adjusted. I don't see the same being true for RoP at all, as it comes off like the standard 'product for consumption only' that we get with Disney and Marvel (think of all the Marvel D+ series: are people even talking or thinking about them months afterwards in positive terms?). Many people now probably can't really remember what happened in specific episodes earlier in the seasons, and a couple months time after the RoP finale people will probably just forget about the show. I wouldn't doubt if Amazon constantly trickles season 2 news between now and the season 2 debut that's several years away, but it's still a long time to where people will just forget it even exists.
