I'm going through some of that "not being able to sleep" thing, and it can be quite sigh-inducing.
I really haven't found that much to bitch about this comic. I spent yesterday and today reading the archives for, I think, the third time (I read them all when I found the comic a couple years ago, and then read them a bit later when I missed some and had to catch up) and it just holds up. Yeah, continuity bits and pieces, but considering Jeph tends (judging from the news posts) to make it up as he goes with only a few pre-planned arcs, it holds up really well.
What really gets me is the time dilation/compression thing. I mean, for the characters a single day -- sometimes a single hour -- lasts for days in the strip, and we end up with a really weird perception of how the characters work. That's just interesting as hell to me when I look at what goes on here on the threads.
If it's interesting enough to read and talk about, it's good. If it's not good enough to read and talk about, time to do something else. No real point in bitching about it anyway. Lots of other stuff to read.
