Quiver

I read it to the end out of habit. Vandenreich arc started interesting but then Bleach was ordered to finish so it got messy with a hasty ending.

I actually dropped the series around the Ichigo Ulquiorra fight, when they both started pulling new transformations out of nowhere. I've been reading about the arcs after that, though, and, honestly, if not for the fact that the ending sounds rushed and terrible, I might have been persuaded to pick up the Vandenreich arc.

Honestly, from the dropped characters, dragged out arcs and tonal shift, it sounds like editoral killed that series. 

Let's see - so you didn't go through the Fake Karakura battle (which is actually just a long series of battles with very little plot - even for Bleach standards). It was so dragged out *rolls eyes* there probably were some highlights here and there but nothing particularly memorable.

Then Ichigo *finally* arrived from Hueco Mundo, got into some fights with Aizen going all the time about how powerful he is.
There was an interesting part when finally Ichigo's father finally appeared. That part was good.

Then the Fullbring arc which was somewhat interesting but it felt like after defeating the Big Bad Aizen the series lost direction whatsoever.

And then Vandenreich which rekindled my interest in the series. There was a large set-up with lots of plots weaved together, old characters put into positions, stakes got really high etc - it could be a good arc, actually. There were some big misteries finally revealed (like, Ichigo's parents' story), characters given plots (this time everybody got something to do)...

And then there's this big NOPE which is like an enormous record scratch and everything rushes to the end completely dropping everything that could be dropped.
