I think it's so neat that you are going to the midnight showing on opening day! My husband is going to the midnight show too, with a good friend of his. He says that he will take me next weekend. :-/ It's okay though, I have to work the next morning and would be a total zombie.
When the LOTR movies came out, I found that there's nothing that can compare to the magic of seeing those opening midnight shows with the rabid fans. Have fun!
I'm taking my Mom, who is also a huge sci-fi fan.
She took me when the first one came out, so it's my turn to return the favor.
I don't go to movies often - last one was LOTR: ROTK but this one I've been waiting for since I was 3.
