Speaking of odd choices, I first encountered John Constantine through the classic Vertigo Hellblazer comics, in which he regularly has to correct Seppos (the only thing that rimes with Yank is Septic Tank) as to how to pronounce his name. Constantine, as in "fine". For some reason, no one that rights or directs the adaptations seems to know this, I'm thinking because they haven't read any Hellblazer. Also Swamp Thing shows up and Etrigan is a major character, so you'd think I'd enjoy this, but the writing and the lack of necessity for the presence of Batman really drags it down. The fight scenes are a cut above the usual DCAU fare, but that may be down to having the magical powers of Constantine, Zatana, Felix Faust and Etrigan to use in the showpiece battles.
Whilst Justice League Dark is certainly one of the better entries in the DCAU New 52 catalogue and let's not get onto the last decade of DC live-action films (yes, I've seen Wonder Woman, we'll cover that awesomeness down the track). Given that I didn't pay for it, I'm pretty happy, but probably won't add it to my physical collection anytime soon. I do need an Etrigan though.
