I've seen this movie 12 times. It gets better every time
This review may contain spoilers. I can handle the truth.
This is a movie that exists because DC dosen't know what the fuck they are doing. They probably saw that people were excited for Civil War and thought;
"Hey let's do that with a Superman no one likes and a Batman no one knows"
BvS doesn't have the right context for us to care but it still could have worked if they used Man of Steel as the proper motivation for Batman like the trailers promised.
Even if they did…
