Broadway's Oklahoma! was perceived to be largely inferior to the acclaimed production at London's National Theatre. Mamma Mia! is not the type of show that would win (or even need) Tony Awards, since it's still here while Millie, Urinetown and Sweet Smell of Success have all long departed. And Joe Egg was a well-regarded production, but Long Day's Journey Into Night was both critically acclaimed AND a box office smash, which pretty much solidified its Tony wins. To paraphrase Pickering, I think you've picked three poor examples.
