What went wrong?
First thing is that all good guys are immortal
That is the biggest minus in series!
There are also some mistakes and not understandings about characters powers...
Spoiler for manga:
And I also didn't like god like Ichigo who had torn apart Ulquiorra with bare hands
I hope Kubo will explain it somehow but till now it was really random
Also we have stuck on fights too much. I like fights but I think we should move on with plot more.
