The plotline was clever, each character vivid (if a little unidimensional), the central protagonist genuinely
engaging, the solution to the mystery amusing, the conclusion to the
action satisfyingly
dramatic, and the overall atmosphere pleasantly bizarre.
This is all the more appropriate since, as a whole, Civil War can be summed as part effective superhero
action / thriller, but also equal parts, if not more so,
engaging dramatic / psychological thriller that features Earth's Mightiest Heroes; though admittedly, while the title might suggest otherwise, Civil War is only really a superhero war movie in a figurative sense.
