Went, saw it, loved it.
I have to say, this was BY FAR the largest cross section of society I have ever seen in a theater for a sci fi movie. Everyone from grandpa to 10 year old kids was packed in there for the early movie this morning, and everyone loved it. I always thought of Star Trek as having the biggest cross section as fans, and while they may still have the gross numbers, I think this has a better representation of every age group as fans. Like sci fi movies? You'll like Serenity. Like Westerns? You'll like Serenity, and LOVE Firefly.
