Decent for what you could expect for 1 hour and 20 minutes. The voice acting and animation isn't that great and there's many aspects that should have been included that aren't, like Alfred. Superman's devolution is done very poorly, as in he will kill a bunch of people, then question it, then kill some more, then be sad about it. This should have been a TV show, not a movie. You can't put a story that relies on slow character changes into something this short.
