Depends on which Star Wars you're talking about.
I was excited for the Phantom Menace, after the horrible first 2 prequels I didn't even bother to see ROTS.
Serenity, hands down.
Still haven't seen the last three star wars.
How is that for an answer.
Definitely Serenity...my husband got me into Firefly and we watched all of the episodes from Netflix. Then, to hear a movie was coming out made me quite happy. There were a couple of scenes I didn't agree with, but overall, the characters and thoughtful dialog were my favorite aspects of Firefly. The character development was so thorough that I think, my opinion here, that those watching Serenity who have never seen Firefly will be really lost. Anyway, excited to see it this weekend.
"Quick poll here...
Which movie are you more excited about? Star Wars or Serenity??"
Definitely Serenity. I watched the show when it was on Fox, and bought the DVD set. I didn't get around to watching it, until I found out the movie was coming out today. I forgot how good the show was.
Revenge of the Sith was a yawn. With Whedon at the helm, Serenity is going to be good.
