You know, for some types of fics I have the same feel, and prefer to wait for it to be entirely done before reading. But somehow this one was different! I think it's because I decided I didn't actually care enough about the plot to try to follow what was going on, so it was just a bunch of shenanigans flying over my head that I didn't need to try to remember the antecendents for.

(Often what happens with me and WIPs is that I'm impatient and curious and I read what little has been posted, decide I really like it, track it on AO3, and then just delete all the update notifs until I get the notification that the final chapter has been uploaded and read the whole thing at once.)
