I just recently watched Disney Nature's: Oceans with my sister last night in theaters. I thought this documentary wasn't going to be my cup of tea, but it was quite good. It had cute moments, epic music scores and visuals and it was pretty funny in some animal moments. I think the only things that I am happy with Disney these days are these Animal Documentaries, the Pixar Films and the latest 2D animated film "The Princess and the Frog". Everything else by Disney in today's generation can just burn to the ground.
As for Avatar being out on Blu-ray right now… I would be with CuteSigma on this one. It's not really my interest either.
