If you loved E.T., you'll probably love Super 8. Lots of similar scenes. My favorite part of the concept is that Spielberg (who co-produced) features kids who do kid-like stuff.
In addition, we got to see the Deathly Hallows 2 trailer. I cannot WAIT for that movie to come out!
On the other hand, we had to sit through the Twilight trailer - of which the only redeeming feature was Jacob shirtless.
