I might be very late to the party, but here are my thoughts:
-Diana finally said "The Cheetah!" for the first time ever. How cool is that? Never happened in JL/JLU or her DTV.
-It was great having Rosenbaum back, but lame that they had to claim he was Barry, simply to tie into the New DC 52. Really? Sigh.
-Cyborg actually served a purpose, which I really liked. I was worried he'd feel like another DC 52 ad-in.
-Nathan Fillion is terrific as a voice actor, and funny. Hope he keeps it up.
-I couldn't believe at first that they were drawing Diana using her (brown??) lasso as a whip and holding it by the very end. That made no visual sense, even for a magical piece of rope that forces people to tell the truth. That thing could be as beautiful a visual as anything a GL conjures up, yet it repeatedly gets downgraded. This time, the downgrade didn't even make sense.
-Green Lantern and Star got the best animation (though you could tell they sped up the frame rate in places)
-The story was decent enough, but the ending was really, REALLY out-there. The Justice League made PLANET EARTH intangible? Um...okay, sure, why not!
-I was really upset and bothered by Bane/Vandal's idea of putting Bruce...where he put Bruce. That wasn't kosher for the medium in my eyes. I fully believe animation as an art can be expressive and daring, but this isn't an "art picture", it's a superhero picture intended for mass consumption. That entire turn of events was gruesome beyond belief, and I resented it.
-Two other shocking moments: J'onn being set on fire and running around burning. YIPES! Given that we hear about this kind of stuff on the news every night, you'd think that maybe they wouldn't want to put it in a cartoon movie? That was pretty awful. The other moment was Superman being shot and operated on. Again, gruesome, but the least of the three.
-I didn't enjoy the whole piece as much as I wanted to. I think that if the producers had an itch to do some fun Legion of Doom stuff, this one movie could have been their chance. Let the villains be entertaining and full of charisma and the heroes heroic and bright and people to root for. Instead, it felt like two stories at odds with each other (Legion + Babel) instead of complimenting each other.
-The swearing is as jarring as ever, and oh. So. Lame. Please DC - stop tossing in swearing to be edgy and cool. It's not working!
-The animation style this time around lead to some of the least expressive, most frozen, dull faces and borderline confusing reactions. There were lines early in the film where I had to completely discount the visuals to understand the delivery (because the faces told me nothing!) It was up to the voices entirely in parts. One guard speaking to Hal outside the caves, for example, had this massive mouth that was moving in a fashion that would lead you to think the guy was yelling - but the voice actor was speaking normally. Very odd. I hope we don't see faces animated like these ever again.
-I groaned at the repetition of Vandal's origins, repeated almost word-for-word from "Maid of Honor". The producers have to know that the geeks watching this already saw JL, and even if they didn't, hearing all about a glowing meteor is totally irrelevant, and if it needed to be repeated, could be done in a more inventive way than another identical flashback. If you're going to throw away a couple of minutes of exposition on a character, please make it a Wonder Woman character for once
-I really liked the voice actress on the Cheetah.
-Didn't entirely love that the Cheetah/Diana fights felt like some kind of girl-on-girl pay-per-view cage match though (thanks to Cheetah's fighter/exercise duds).
-Star's design was pretty horrible. She was a total anime mess, though I know she usually looks like that these days.
-Jimmy! We got our Jimmy back for another turn! Loved that. I honestly hope he gets other work, because he always brings a smile to my face when I hear him.
-Did not care for the intro/theme music. Chris Drake did the GL theme, right? I liked that one, whereas this one felt like the 10th superhero movie theme he'd done, and he was over it, and wasn't inspired in the least. With a title like "Doom" you can do some interesting spooky things, and this had none of that.
-It wasn't clear to me whether we learned for sure that the funky tech came from Vandal. Even if he claims it did, I still expected some kind of Fourth World epilogue with Vandal thanking Darkseid and him going "You fool - you failed in your attempt, so now I must come and conquer - Muahahaha!"
-I was surprised to get a kick out of seeing Hal and Superman working together - IN SPAAACCEE!
-No real love for the Flush gang, but I liked how funky their costumes were this time around. That was a nice switch.
-Going by the storyboarding, the League seemed to be literally chasing the Gang in circles for a few minutes at the end of their robbery. What was that? Was GL really flying around some circular hallway endlessly?
-Superman needs to remember his heat vision can and will always be able to cut Metallo clean in half, every time, in under five seconds. Honestly man.
-Always glad to hear Kevin, Tim, Susan, Michael and Carl. Yay team!
It's difficult to say I really enjoyed it because...I didn't. It didn't charm me or really annoy me. I wouldn't watch it again, and wouldn't buy it either, though it was well-done in many respects and I liked the cast. I just feel like these movies are interchangeable and aren't leaving much of a mark on the world of animation or superheroes. They're not a cheap cash grab, but they're not Feature Film quality either. If this exact script was made into a Live Action film, they're change and cut stuff and tighten it in places. I can't figure out why that wasn't done here (losing the pointless Vandal origin, maybe setting up the Hal/Carol "they broke up and it was ugly" history a bit, doing something to show newbies why Cheetah and Diana fight (one line does not a relationship explain), etc).. These JL/Batman/Superman movies all feel like they're aimed directly at the DCAU/comics crowd, who already know 90% of what's happening. So...it's hard to get excited about these. I wouldn't show this to someone who knows nothing about the characters. I'd really like to see their next DTVs break some new ground in some way, and stand apart as a really successful piece of artistic expression. This was an okay movie, but not that.
I'd say this one is almost as good as the Red Hood movie, though I liked that one more because it had the potential of being a terrific, sombre character-driven movie of Feature quality (and fell short).
Dwayne is missed.
