...Because they don't have to be. Up was an amazing movie.
Sorry but UP (IMHO) was the most overrated film I saw this year. Predictable plot, really BAD 3D (it was like looking at an aquarium) and they pretty much stuck with the CG animated formula. That's what I disliked the most about this movie, they took no creative chances.
...Clean coal and clean air is the real solution, but destroying any R&D, even for a temp-solution, is definitely not a solution.
There is no such thing as "Clean Coal" and if you think the current administration will not realize this think again: Big coal was a major contributor to Obama from early on in his political career.
