Best League Member?
It was initially looking like they were somehow gonna make this a Batman story, but he was just a curmudgeon along for the ride. He kinda wins this one by default due to the lack of everyone else, but his characterization was on point. O’Mara by this point had also settled into the role well enough.
Weak Link?
There is nothing funnier to me in the world of DC than that magic is the great equalizer to Superman and Green Lantern’s powers. Top notch stuff. You suck, Superman. Wizards will always get the better of you.
Worthy Villain?
Jeremy Davies himself did some great work and was a welcome presence. His character and the shit with the demons was kind of dull It may just be a natural consequence of this corner of DC stuff, but I suspect it is because having so many JL Dark team members at play needing an intro or something prevented any true investment in the larger story of the film.
Recommendation?
There is nothing here to be really excited or angry about. The needs of the premise kind of put them behind the eight ball with so many “new” characters in relation to the normal Justice League squad that it was near impossible to do well. Naturally, it was nothing special as a result. Mild Thumbs Down.
