Expecting another lame kids story or remake, I was pleasantly surprised to find this movie added some new twist to the old story. The plot line followed much of the books, but there were some alterations of characters and plot to build to a more climatic end.
After seeing Avatar in 3D and then seeing this in 3D with iMax, I have to say, Avatar wins out. I'd have to say this movies recreation got an "A." For me, the let down was the some unresolved plot lines.
If you're just looking for an amazing studio generate movie and neat affects, it's well worth the money.
