There are 3 reasons I HAVE to go to the cinema this year:
1. The Fantasy Filmfest (>20 movie premieres in 8 days, I visit it every year)
2. The Dark Knight Rises
3. The Hobbit
I know nothing about it yet (except for the villains), because I did not watch the trailers, teasers and promo whatsoever stuff. I just expect the best and I am sure Nolan will deliver
Actually I don't know if I prefer a Happy Ending or a sad one... let's just hope nobody will spoil it for me. What I want are some nice surprises and the typical dark atmosphere. The rest is up to Nolan, I trust him.
Will it be better than the first two parts? Maybe, but it does not have to. They were so great, it will be very hard to top them.
When I look back at famous trilogys there are some good examples for amazing 3rd parts (Indiana Jones, The Lord of the Rings, the new Star Wars trilogy... okay, the first two parts of this were easy to top), so I am not worried about it.
