Complicated sounds right. The big Dallas "Bobby is dead, but Pam was only dreaming" storyline has been brought up here. The fix on that one was simple. Bobby was hit by a car two seasons ago and was in a coma for a year. J.R. didn't want the public to know for fear it would hurt the Ewing Oil stock. Then Bobby woke up. Done.

I'm sure the same kind of thing could have been done with Spider-Man.

I wonder what the folks at Sony Pictures think about this turn of events? They certainly cut across the grain of the storyline in the movies.
