It was good. Not the best of the DC animated films, but far from the worst.
Much like Batman/Harley Quinn, this certainly could be taken as an official DCAU movie if you close one eye and kind of squint with the other, despite deviations from previous continuity. It looks like it, sounds like it and feels like it - and that feels good.
The visuals and audio cues are near-perfect. The designs are Bruce Timm at his best, and the return of the DCAU voice cast and half a dozen musical callbacks certainly hit the nostalgia button right between the eyes. The action is top-notch as always. But the script is a bit wonky. (the LSH sends its prisoners to the past? Huh? And then they don’t bother to come help when something goes wrong?) And the new characters aren’t fleshed out in a satisfying enough manner - though much of that is due to the typical 75ish minute run time.
Jessica Cruz, for instance, is a fascinating character in the comics. I loved seeing some of her history presented here, but from some of the marketing material, I was under the impression that the script was going to really tackle the issue of mental illness, especially with Jessica and Thomas. I suppose they didn’t do a horrible job for a 75-minute super-hero film, but it was certainly a much shallower exploration than I was expecting, especially after that opening scene with Jess.
The film just needed a bit more follow-through to really be a home run for me. Miss Martian’s complex Young Justice personality was watered down here, Mister Terrific didn’t get nearly enough screen time and we got absolutely no closure concerning the events on Oa.
Just give me fifteen more minutes of movie (without any more action scenes) and I’ll be happy.
