The MCU has made some fun and successful films. All adaptations take liberties with the source, but the MCU seems especially prone to giving us in-name-only characters. Sometimes (Wong) that's for the better. Others, it's not, especially when Marvel has so deep a bench of characters that can serve the role Feige, et al. wanted for their scripts.

My case: Sam Rockwell gave us fantastic character in Iron Man 2, but it wasn't Justin Hammer. However, the film's character seems *very* well suited to the comics' Morgan Stark.

Others?
