Eh not sure why people would expect huge box office. Blade Runner is pretty damn close to being a full on art film, lol, it's not some fantasy action franchise.
I believe Ryan Gosling has one total film in his career that made over $100 mill domestic and that's La La Land, largely off Oscar hype. He's not exactly a huge box office draw. $35 million would easily be the largest opening of Gosling's career I believe. Harrison Ford hasn't been a real movie star for like 15 years.
$35 mill opening sounds about right to me. 89% is a good RT score, but it's not like it's some unheard of/impossibly high standard ... Spider-Man Homecoming, Wonder Woman, Logan Lucky, War For the Planet of the Apes, A Ghost Story are all above 90%. Heck, Girl's Night starring Queen Latifah also is 89%.
