Well, it's already stated in my description.

I basically thinks that finally, the already-long-time-lousy Ichigo has started to give us a real good show in the recent manga chapter 350.

I find his transformation to the higher stage of hollowfication (I assume) is pretty impressive and drastically reduced the bad impression on his bad performance after his battle with Byakuya in Rukia's arc.

I think everyone thinks Ichigo is lousy is because of numerous lousy (once again, the word) nonsense fillers which keep appearing in the anime itself, which portrays Ichigo's skill has gone dull or some sort. But in manga, the Hueco Mundo arc starts right after the Rukia's arc, so it doesn't show much of Ichigo's lousiness.

But then still, will Ulquiorra catch up with Ichigo's sudden change? Is Ichigo still perfectly a living human or a Hollow or not even both? Is this transformation related to his father's past or it's perfectly because of INOUE? (I'm an anti IchigoXOrihime)? I'm very very very curious.

So what you all think of his recent transformation? I welcome any comments on my statements?

I wasn't too surprised by Ichigo's transformation as in almost all of his important battles, whether Ichigo intentionally did it or not, his hollow is the reason why he wins.
I think he will eventually snap out of it and ultimately learn how to control his new power because after all, he is the main character and more than likely he is gonna fight Aizen eventually and he needs to get stronger somehow.
