I'll give you a tip of watching the BLEACH MEMORIES OF NOBODY. It should be watched after BLEACH's 109th episode.
Also a tip when to watch BLEACH The DiamondDust Rebellion mouhitotsu no Hyourinmaru - it goes after 154th episode.
I can say about both movies that they are not so interesting or exciting as the series.
Gekijouban BLEACH jigoku hen is after 302nd episode.
The transition to a filler section of the series from episode 167 to 168 was awful, without any explanation they just started it like there was never the story about arrancars... duh! At least they tried to joke out to a continuation of the main story :D
Er... why they wanted to execute Rukia for her relatively minor offence, and just sentencing Aizen for prisoning???
