Every fantasy and sci-fi show does an alternate/parallel world episode. "Let's make the good guys act like bad guys, and the bad guys act like good guys. The normal good guys cross over into the alternate- reality and defeat the new bad guys. While we're at it, let's put two of the good guys (who are now bad guys) into a romantic relationship." It's the sci- fi version of the sitcom "bottle episode" and is rarely well done.
This variation of the theme is worse than most, and for Justice League fans, the randomly chosen set of celebrity voice actors makes the whole production just seem fake - i.e. good superman and bad superman both sound wrong. Alternate-world episodes usually seem to be driven by actors who want to dress up and "act" differently. But in this case the unfamiliar voices of the characters only works if the script is exceptional (like in Flashpoint Paradox), but in this case the story and script and very bland.
The entire movie just falls flat.
