Lacks lusture, poor direction and story telling. Awkward story jumps make the viewing experience unenjoyable as there's no linear flow of the story. Steppenwolf is puny and is barely intimidating, watching him doesn't send a shrill up the spine. Ben Affleck doesn't justify and make sense out of the Batman and still enjoys considerable amount of the movie time making the movie look less about the team and more about himself.
Lastly, you won't yawn but you wouldn't regret giving this one a miss either.
