Ten-year-old me would've been woozy with excitement at the prospect of a Justice League movie. Having sat through Zack Snyder's deadening Man of Steel and Batman v Superman: Dawn of Justice, nearly-50 me was just praying that the Snyder-helmed Justice League wouldn't suck. And it doesn't. But I really should've been more specific, because I forgot to also pray for this superhero saga to be good.
