Btw I can't believe you're not enjoying shirobako that much. In terms of fun and humor this is the best thing PAW has done and is definitely the best series they've made since uchouten kazoku and tari tari.
I'm not sure I'd consider Ore Twintails ni Narimasu a true "watching for lulz" show... it's too sincere and has a higher tongue in cheek wit to fanservice ratio than Unbreakable Machine Doll, Seikoku no Dragonar or Seirei Tsukai no Blade Dance. All of which I watched in full as they were airing.
BTW I decided to make up a list of who has licensed what PA Works stuff for US/Canada distribution:
Bandai (AKA license Limbo AKA out of print): True Tears
Sentai: Canaan, Angel Beats, Another, Tari Tari, Glasslip, Shirabako
NIS America: Hanasaku Iroha (including the movie), Uchouten Kazoku, Nagi no Asukara
Funimation: Red Data Girl
Unfortunately, I'm well over the Anohana, Key, Nagi no Asu Kara-type like moebaww dramas. Also doesn't help that Shigatsu is airing in the same season which I'm absolutely loving and is just superior in every way.
EDIT: Just watched it and whilst it was better than the other two episode, it didn't do much for me. I think I just got really hard to please .
