The recent Direct to DVD movies have been good, solid movies IMO, just not amazing on the standard that Bruce Timm fans have come to expect from his work. He blew us away with JLU, and these brief little movies don't have the same impact as the show did.
Superman: Doomsday had good emotion, fight scenes that demonstrate how a big-budget live-action Superman should fight, and an interesting (if disturbing) take on Lex Luthor. It just seems a little "been there, done that" since Doomsday showed up in "A Better World" and "The Doomsday Sanction," while the emotional response to the death of Superman was done in "Hereafter." The movie came across like something Bruce Timm was pressured into doing, because the comic story was so well-known.
New Frontier suffers from the length of the source material being adapted, the huge cast of characters, and the limited running time. The voice actors were well-cast, and the movie was good at creating moods and taking us back in time. Several characters, most notably Hal Jordan, have the the foundations of a really compelling story behind them. But there just wasn't enough time to go around. The movie felt a bit like a series of vignettes. By the end its messages of tolerance and unity were communicated, but not with as much punch as the movie could have if it had been longer.
Gotham Knight was advertised up-front as a series of vignettes. It was therefore scattered, but not as much as New Frontier was because it only had one hero to focus on. The movie's problem is the inconsistent writing between various vignettes. A lot of big-name creators were brought in, but not all of them lived up to the hype.
The first vignette, "Have I Got a Story For You," was a cliche stock story that had already been done in the episode "Legends of the Dark Knight." I don't know how they didn't pick up on the similarities, or if they did, judged that the fans wouldn't notice or care. I also can't believe that they thought this part would be a good lead-in to the rest of the movie, since it was goofy, kiddy, and completely unnecessary, while the rest of Gotham Knight was dark, dramatic, and interconnected.
"Field Test" was also hampered by mediocre writing. The purpose was to show Batman's strong sense of morality, and his compassion for the very criminals he fights. That's a worthy goal. However, the execution was lame: a young punk gets hit in the shoulder by a bullet ricochet, causing Batman to frantically rush him to the hospital? At one point, the punk says "You've killed me" which was just a total exxageration. The vignette ends with Bruce retiring his forcefield device because of the punk's injuries, capping off the series of overreactions. The point would have been made much better if the punk actually suffered a serious injury.
And while Gotham Knight was partially intended as a showcase for various anime artists, some effort to enforce a bit more consistency would have been nice. It was a midquel to Nolan's movies after all. Batman looks like a manly badass in some parts, and a bishounen pretty boy in others. In the first part, he notably looks like a poorly-drawn fat guy. What was up with that? They couldn't decide on whether Batman was wearing the Batman Begins armor, or gray spandex. Sal Maroni gets taken down in "Crossfire" (part 2), but is the villain again in "Field Test" (part 3). Batman is apparently BULLETPROOF in part 2, which confused the hell out of me. Was that just over-stylization in the action? Or was it a reference to the forcefield in part 3? But then, when do those two parts take place in relation to each other (see Sal Maroni)?
The second half, with Killer Croc, Scarecrow, Bruce's training with the Indian woman, and Deadshot was better.
Overall, I think Bruce Timm and his guys haven't really been given the chance to make something great yet. Superman: Doomsday seemed like a chore, and New Frontier and Gotham Knight's fractured formats made it hard to tell a story. I still liked them all, but I know that the people behind these movies are capable of more. I'm looking forward to Wonder Woman, which doesn't look like it'll be handicapped the way the others were.
