I thought this episode was great fun, it ran smoothly, didn`t draged anything and was entertaining the whole time, Aizen seemed really threatening too, i don`t particulary see any huge plot hole, we have to face the fact that Aizen`s sword is a huge ass deus ex machina. [/opinion]
My only complain with this episode: Why can`t those idiots use their Bankai already!?!?!?!?
