Well, you might want to add some context to that record, LOL - it was a bargain priced re-release that was thrown up in a standee in every Wal-mart and heavily discounted ("
Avatar can credit its resurgence on the home-media sales rankings to Wal-Mart's "Value of the Day" deal that marked down the price of the film by 75%", per several media reports). It was also done on a slow week for releases, to boot. It only takes the low five digits to be the best selling Blu-ray on an average week. I bet if they put canned sardines at the front of every store and discount them 75%, you'd see them sell pretty well, too.
But like you say, it's already been explained - Avatar really made little
cultural impact, it's pretty much forgotten in the discourse today, the only reason the first film did the revenue it did (and it's the revenue that was king - it's not even in the top 10 of most tickets sold) was because of the 3-D tax and the big new introduction of 3-D to audiences so everyone and their grandma went to check it out during a slow box office time to begin with.
Today, it's a crapshoot when you say "Avatar" which one you are even talking about as it has the same name of a very successful children's franchise, and just about everyone you could ask would be hard pressed to name a single character, give a single quote from it, or really say anything other than "it was pretty". In short, it has no emotional or cultural resonance. Kids aren't buying Avatar toys, you can't buy Avatar lunchboxes at Wal-mart, there is no franchise to speak of.
All that said - you are correct - it's the attractions that count. The point was, there is no rabid fanbase of Avatar fans waiting for it. Even the best case scenario, Soarin' 2.0 and a boat ride, aren't going to change the game in Orlando. It gives a park that desperately needs new attractions some, but it's not going to bring folks from all over the world that are just chomping at the bit to get them some Avatar.
