I think as storytelling goes, part 2 was better than part 1. It had an action-movie feel toward the end, even though the CGI aircraft were a bit cheesy.
All in all, a faithful rendition of Ayn Rand, and actually fun.
You're watching a railroad and metal company battling the govt, and every 20 mins some guy talks to another guy and he's missing.
Who cares who Midas Mulligan is? If you haven't read the book after watching part 1 you don't even know he exists.
