Query: Mediocre

The one-star rating is because justice league doom is simply not worth buying.No better or worse than a standard justice league tv episode.If Warner's wants to continue the show through DVD releases then they should use the familiar animation style along with the regular voice actors.Aside from red hood and I suppose crisis on two earths, the dc Warner's direct to DVD releases have been mediocre, uninspired, and honestly somewhat boring.The whole pg-13 thing just makes these projects too heavy and somewhat depressing and needlessly violent to justify the rating.The fact the brave & bold and young justice were/are so entertaining seems to prove that dc characters fare best with an ongoing series, where a 75 minute cartoon or even a 2 hour live action film just doesn't serve them well ( Nolan batman movies excluded).
