The reason the show isn't clicking is because the show has delved into the almost mythical badass Boba Fett AND the Boba stuff has been kinda mediocre. People only cared about Boba Fett mostly because of the mystery. Now that we've peaked behind he curtain, it's not that interesting of a story being told and the Mando stuff is SO MUCH BETTER.
Boba Fett had just over 6 minutes of screen time in the OT and they managed to make him feared and build a lot of mystery around him. IMO though, LucasFilm should've left him in the pit and just let the character live on through Din and the other bounty hunter characters.
But let's be real, people didn't love Boba because he was an awesome character. People loved him because he looks cool. All Bounty Hunters or Mandalorians - whether it be Jango Fett, Boba Fett, Bo-Katan Kryze, Din Djarin, The Armorer, Paz Vizsla, Koska Reeves, etc - inherently look cool. Almost all are fan favorites, too. But that doesn't mean they should all get their own series. There was no story to be told here that couldn't have been told in Mando S3 imo.
