I had no idea what to expect prior to watching this other than I know Swamp Thing was going to be in it. This turned out to be Constantine being the main lead, and Batman had little part to do in this team even though he is placed largely at the forefront of the cover art. I giggled at each time we got the "_Hmm._" from Batman, and his silly one-liners, haha. I've never seen Zatanna, Boston, or the Demon in action, let alone working together as a team before. Whenever I see the Demon, I think of that time when he teamed up with Lobo in the short mini-series of comics. We get a little insight on his origin in this one. The House of Mystery makes an appearance (as seen on the cover art). I was mostly excited to see Swamp Thing, and boy was he awesome in this; fought valiantly, but wish they had gone at it in a team. Although tragic, there was probably more deaths/bloodshed seen in this one than any of the other animated DC films. I sure hope there would be a Justic League Dark sequel sometime in the future. It's a nice conjure of mystics, magic spells, illusions, the night, demons, and a spooky horror-like atmosphere fit for the Halloween time. It was definitely worth my rent on FandangoNow.
