I think they wanted a less scary and less hopeless trailer
It's not a bad trailer, but I suppose it just feels tonally different than usual. The music sounds like something out of a gritty cop/crime movie, but the voice over does speak to series fans specifically, while broadly being a sort of halftime locker room pep talk.
It's less bleak, I guess, instead focusing on the hard won triumph you may eventually earn. Neat.
March 11, guys!
