Avatar was a fantasy, and not as silly as the phony WWII history "Inglorious Basterds". The plot was secondary to the FX, and of course it was silly. Having an enlightened White guy to save the Pandorans was a bit like the Japanese hiring an American actor to save the Japanese from Godzilla in the US version of that film. So that was also a tad silly.
As for shampoo, the packaging is directly related to price: the fancier the package, the more it costs. I tend to only expect clean hair from my shampoo. Conditioner is better when in a single product. If you want to smell really nice, cologne lasts longer than any scent the shampoo might leave behind.
I do not think that one woman writing one article can actually mean that all women feel the same way.
