For another, the details of the heist are far
more complicated with a lot of moving parts and ancillary characters, such as Dwight Yoakam's prison warden, who have no idea that they are playing a part in Jimmy's
grandiose scheme.
The studio seems to have taken in feedback, though — Marvel has a villain problem — and Kaecilius is given additional layers that Ronan lacked, nuances to his evil
scheming that result in an antagonist
more interesting than
grandiose plans to destroy the universe.
