I loved this anime, all in all. I've liked it every since I was a kid. However, I didn't enjoy the insane amount of fillers. If they would've stuck to the main plot, I would have no complaints as for as plot goes.
Many people say that the season went bad after the (I'll say it this way so that it's not a spoiler) big fight, but I disagree. As far as character development goes, continuing the story was a good move. I'm not only here for one set of foes, I'm here for Ichgo and the supporting characters.
I gave sound a nine because I didn't enjoy the changes the made in the voicing. I figured most of that couldn't be helped, therefore I only deducted one point.
I give it an overall nine simply because of the miner bugs in this seasons.
The final episode was the best I could've asked for. I would love to see another season.
