I hated the trailer on first watch except for a few shots. After watching two more times, my feelings have kinda reversed.. kinda.

-I hate that soccer ball droid. How's his R2 head staying on? Looks so silly. I just can't understand people saying it looks like it was plucked out of Star Wars (ANH).
-I hate the stupid cross lightsabre and it's fiery blades.
-I Hate that the dialog (and title) are all about the force and light/dark side. The Jedi stuff is the least interesting thing about Star Wars to me.

There are some things I like though.

I'm hoping the full trailer will have more of a 'Star Wars' feel and less of a 'any new blockbuster' vibe.
