Solid post.

As you mention at the end, the movie lacked a solid villain, IMO, like Civil War. You never felt real danger. All that changed with the ending, though: my jaw dropped.

Any examples of cool superheroes that get the science right? Seems to me it's hard to make any that aren't variations of Robocop and the Terminator. To be fun, it must be somewhat scientifically inaccurate, it seems.
