Soooo first teaser got 58M views, and now the trailer is at 21M after 3 days. We know that views are at their best in the first 24 hours and it's only getting slower and slower after that. I can't see it going above 35M.
Looks like people saw the teaser and "noped the fuck out" and didn't even watch the trailer. I honestly expected some big, big numbers like at least 70M views but here we are.
Some context: the MoS trailer from 12 years ago, so much less people on Youtube (800 million in 2012 vs 2.5 billion now) has 51M. BvS is at 79M and even Aquaman has 66M and I'm not even talking about Godzilla Vs Kong which broke everything with 109M. Joker: Folie À Deux had trailers that reached 34 and 37 million. The Flash is at 32 million & Blue Beetle 31 million.
I've talked on another forum that what will make or break this Superman is the GA, and it looks like they don't really care? These are only views on YouTube, it's not enough to judge the future success (or not) of the film, but... yeah, I'm vey surprised.
