Spiderman 4

[Kybo Ren]

The Leader, while awesome, but somewhat reminiscent of a longstanding Gargoyle (god i love oldschool hulk)- is too smart for a thing/hulk. granted the first act must be thing/hulk slugfest, Leader is too damn intelligent for them to take down
UNLESS...
thing&hulk run an over the top obstacle course forcing them to work together to even get near/at the Leader, only to have them FAIL at the coup de grace. and then out of left field steps DrDoom to take hulk for experiments, leader for slavery/experiments, and leave the thing to report back to RICHARDS! to show how impotent they are in the face of Doom. he would want richards to have all his toys when he finally takes that stretchy jackass down.

still not confident about new abomination (Roth good, Abomination uglier/not ugly enough)

Have always wanted hulk movie to show gamma mushroom cloud, and have everything high speed around bruce until he comes to screaming in doctors office.

and to stay on topic...
Jake Gyllenhaal replace spidey in 4
Maggie Gyllenhaal replace mj in 4
Luke&Leia seem less creepy
