I'm pleased with 3-5. Haven't seen Avatar yet.
Seeing the Harry Potter films so high makes me realize how many shmucks like me there are in the world - guys that go see the movies day one simply because they're Harry Potter, despite knowing they'll be shit compared to the books.
Also, to those mentioning inflation, recall that movie theaters are expensive as hell these days, regardless of any change in the value of the dollar. Yeah, prices have gone up a decent bit in the last thirty years, but movie ticket prices have double in just the past five or so years, from around $5 to $10 in my area. I also find that ticket prices vary heavily by region. Big cities have $10+ tickets, while small towns in the middle of nowhere are still around $4-5 like they were several years back. Theaters in heavily populated areas increase prices on a whim simply because they know they'll be selling out anyway. There's a bit more than mere inflation at work here.
