"Don't forget to have fun out there!"

But...that's what these films are about. :p

Heh heh, I know, I was just being hypercritical (and trying to be funny).

I mean, the briefing isn't awful... but there are a lot of things I don't like about it. And of course, these are supposed to be fun movies, but it just doesn't seem like the rebels are taking this battle very seriously when it seems like anyone can just be a general, Luke barges in to say hello, etc. I know they're supposed to be rag-tag, but they just don't seem like a professional military.

It's kinda goofy and minimizes the sense of impending danger (for me anyway).
