I still can't for the life of me figure out why they handled the end of the anime so horribly. Why on earth would they try to cram all that stuff into so few episodes? -facepalm- They didn't have enough canon material to keep going... yet they completely cut at least one full (if relatively short) story arc... Totally logical, that.

If anything, they HAVE to do the Bone Youkai arc (and subsequent poison/sake arc) to explain why Sango's Hiraikotsu suddenly is much more deadly against Naraku...

I'm a pessimist at heart. I honestly don't expect them to include any of it, because the track record is wishy-washy (they added Mir/San filler episodes, but removed canon ones and so on). There are scenes and plot arcs that I hope get included... but I have little faith in the creators after seeing the "conclusion" to the existing anime. XD
