And as Nightwing noted, the Superman/Lois flight scene was similar to the X-Men - but seeing the way Superman ripped the wing off of a plane makes me hopeful that there will be a lot of original stuff here too.
The flight scene is similar but not identical...the vibe is very different. I like that Lois stands on Superman's feet to be lifted in the air, the way a little girl stands on her daddy's feet to dance. It's sweet.
But as for the wing thing...if this is the plane (near)crash I've heard alluded to in spoilers, it would seem the wing comes off because Superman tries to catch it by the wing and it turns out to be a bad idea, forcing another tactic. This is pretty much what happened in the first episode of the Animated Series...Superman tries to catch a crashing plane by its tail, but it breaks off so he has to regroup. So maybe it ain't so original.
