About Hanasaku Iroha,are P.A works the only ones producing?Normally you see a "production commitee" or at least more than one company,but here all I see is PA works.
For exemple True Tears had Bandai behind it , angel beats had aniplex.
Also,there's still to me this contraction of PA works biggest seller being Angel Beats and yet that show is the one that feels the least like it comes from them.
Now there's the fact that Angel Beats is the only (major) P.A works anime without Okada Mari involved in the script,but also animation wise,the Chief animation director and character desiner has been the same for all shows except Angel Beats!:
Sekiguchi Kanami (though she still worked on Angel Beats! in a lesser position).
Hirata Katsuzo , who replaced her,and that's Hirata 's only involvment with P.A works.
Mabe that's why I feel that the look of the anime isn't quite the same as the others
So when 3 out of 4 shows share the same scriptwriter
