TFW Bleach Filler caused me to drop the series entirely.
It was on thin ice with all the BS Aizen was getting away with. The constant filler arcs was the breaking point.

Anyway, filler isn't entirely a bad thing. It can get annoying when used constantly, but it's not the complete antithesis to a story.
But just because you find an episode boring doesn't make it filler.
