Just saw Avatar in 3D, and it was quite good.
As some have said, the storyline is predictable, but practically
the entire movie qualifies as a "special effect" and there are definitely
some messages in there for the populace.
I liked the final major battle where it looked like all was lost,
and they realized their prayers had been heard when the animals
converged en-masse to join in the fight against the invading humans.
Got quite rush of emotion from that, which is rare for me.
I would recommend this movie...
