ST Should I go the niht it premires or not?

So, the big question. When are you going to go see TFA?

I see two scenarios:

1. I go to see TFA at the first available showing . Its a large group of rowdy star wars fans. The movie starts... and so does the screaming and yelling. Lit lightsabers everywhere....

For anyone with experience of movie premiers like this... is it likely if you go to the first showing that you will miss half of the movie? I mean there's a certain amount of excitement that's expected, but will the first showing be more of a 'being there' kinda thing than 'watching the movie'.

2. I go to a later showing. There's that one jerk in the audience who half way through the movie shouts "Vader is luke's father!" (or TFA equivalent) and spoils it all.

I really want to go... but I'm just not sure.

Any help form the Masters on this one would be greatly appreciated!
