I remember thinking that the "Death of the Family" arc in Batman looked interesting a few years ago. It took near an entire night to find the necessary guide to all the different books I needed to read and acquire them to get the entire story.

Only for it to be almost meaningless in the greater canon, including a major character being forced out of what should be one of their most important stories and then retconned to ignore it ever happened just because the author of the "main" book for that character didn't like it ruining their "vision" for their run and not wanting to play along. Among them deciding another "major" arc needed to follow Death, so basically all the consequences from it to be moved on from despite how huge it really should have been.

On the other side, I find manga that look interesting every few months and the biggest hurdle is sometimes finding the name and after that I'm reading it in a minute. Wherein the only possible obstacle is slow/bad scanlation from there.
