So let's run through the list:
10. Wreck it Ralph. Seems interesting in a Scott Pilgram meets Toy Story. Gonna have to wait for more info though.
9. Iron Sky. And a lot of people think that Japan has a stranglehold on "bat s*** insane." Of course, this might explain why "History of the world pt 2" never saw the light of day.
8. John Carter. Ehh... Don't get me wrong, it seems like a good premise, but if it has a reason for not being touched before and production had had a large number of problems, I can't say I have hopes for it.
7. Brave. I always thought Rapunzel in Tangled did it first, unless you meant as a "primary goal of a hero" as opposed to "forced into the role reluctantly." Still, it's a Pixar flick and even their worst is head and shoulders above the competition.
6. Lincoln. Oh dear. I'm sorry, but big actors means big egos and this is supposed to be something that's a sort of docu-drama. I can't see it going it well. A pass on my plate.
5. Prometheus. About the only real twist I see is that it's supposed to be an Alien prequel. Everything else you said about it has been done before.
4. As said earlier in this thread, better suited as a documentary on discovery as opposed to a full length feature film.
3. Django Unchained. Now I know Tarantino is simply aiming for "lets get people screaming against this film" approach of film making. Yeah, let's bring the situation into the sunlight, but I'm not sure I want HIM doing it. Also see my stance on Number 9.
2. The Avengers. If they do it even nearly as well as their previous efforts, it promises to be a good summer blockbuster. Now if they push it away from the SBB period...
1. The Hobbit. This is Peter Jackson taking on Tolkien again. It would take an absolute insane level of apathy to screw this up.
Special. The new Batman film. I agree with the Meh. The hype surrounding it is the hope that The Dark Knight wasn't a "lighning in a bottle" scenario and I just don't see it happening again.
Anyways, that's my take on the list.
