I hate to point this out, but....
The reason DBZ, Digimon, Naruto, Poke'mon, Yu-Gi-Oh!, Sailor Moon..............
and so on..
do well in resale, is because people (other than "Fans" know about its existence.
these are series that have circulated around and around thousands of times on
networks (other than just Cartoon Network) ie KidsWB and FoxKids (1996-2004)
Back then Everyone knew about anime because it was still all very MAIN STREAM
Now days, you can't even find anime on store shelves anymore UNLESS they are
DBZ, Poke'mon, Digimon, Yu-Gi-Oh!.... so on and so forth. These series have
become one with our society in every way.
However, SHAKUGAN NO SHANA has NEVER seen 1 iota of a minute on MAIN STREAM
television *United States Cable Services* (This does not count Anime Network
nor the supposed "FUNimation Channel" which I'm still not convinced even exist.
And if it does, it must only be for VERY select cities. But even with that,
the average audience isn't going to watch "FUNimation Channel" unless it's
FREE and available to everyone (just as Cartoon Network is)
Most of my all-time favorite animes are series that have NEVER seen 1 minute
or United States air-time. (Although TechTV was largely responsible for my
obsession over anime in the first place. Otherwise I too wouldn't have seen
half my titles.)
Walk into Walmart or Target some time.
Look for a FUNimation title in the Video Section.
Then if you DO find one Tell me if it is one of the basic Main Stream animes
that became popular in the "Pokemon/Digimon" Era.
(--Side note, I'm still asking myself "Where's the DVD/BD release of Monster Rancher?)
