I'll respond to your comment even though it is likely to be deleted for your completely inappropriate language. As "wikia's walking Bleach encyclopedia" as I was called for a long time, I can answer many of your complaints. First, Ichigo. The point of Ichigo during the fight with Aizen is that only Ichigo has the strength to weaken Aizen to the point that the seal could work. Urahara's seal could not restrain Aizen at his full power. It took a hit from Mugetsu in order for Aizen to be weakened to the point that he could be sealed. The blow was so powerful that the hogyoku rejected Aizen as its master and stripping him of Kyoka Suigetsu. That is the point of Ichigo, because without him, Aizen would have succeeded (which he should have =P).

Secondly. Shunsui was not incompetent. He made a tactical decision. He put two strong opponents up against one another knowing that only one would walk out but he did not know which one. The point of this was that he was willing to sacrifice the leader of a team of healers in order to awaken a weapon of massive power. There are other healers in Soul Society but now there is no one as powerful as Kenpachi. That was the point of them fighting.

Kenpachi did not pull any of this out of nowhere. Kubo has hinted from the beginning that Kenpachi can get stronger. In the non canon novel "Spirits are forever with you", Kubo praised the author for giving Kenpachi the ability to make himself stronger. He stated that he had something very similarly planned for Kenpachi in the manga and was surprised said author could pick up on the hints he left throughout the series to this ability. So no, he is not a Gary Stu, this has been coming for a while, you just didn't pick up on the hints

As for Unohana, she didnt just lay down and die. She fought to the best of her abilities, killed Kenpachi several times and brought him back each time but she ended up taking a fatal blow when Kenpachi reached his former strength. She did what she had to do for the benefit of soul society. There are other healers in Soul Society, with her gone, Soul Society can still heal people.
