I've been following this strip since before the turn of the century.
It's been a good ride and it has outlasted many of the other online comics I used to follow and while the quality may have been variable, it never dipped to the point I wanted to quit reading.
And the creator is a master of the slow burn, his story is incredibly dense filled with amazing reveals that show that he had it all plotted out years ago and delivers us these reveals with the patience of a Buddha.
To his credit he had decided to wrap up this magnum opus in time for the 20th anniversary and he would take the whole thing off on a lighter tangent.
We're now almost two years after the promise of the reveal and we're nowhere near any resolution since the comic is now going on hiatus for two weeks and there are hints that we may not get the final reveal until another long goose chase of indeterminate length.
I don't mind running the Marathon, but if you notice that somebody is moving the finish line further and further so they can add another ten updates telling this joke and twelve setting up a situation that leads to another fifteen of nail-biting tension, and while there is a progression, the final resolution keeps slipping away because other than a few details I don't see that many unresolved plots yet to be dropped unless the writer figures we're due for another three year long interlude to explain the rest of the backstory before finally throwing the switch once and for all.
Sluggy has really good and really bad moments, that it lasted so long is a tribute to the writer and the fans, but two years into seeing any resolution and hints that it could last even longer before it finally happens … Feeling really tired about it.
