This is the 3rd team up episode of THE BATMAN within 5 episodes, and it proves that so far they have a clear formula. One of the guest hero's rogues randomly decides to commit a crime in Gotham for whatever reason. Guest Hero arrives. Guest Hero gets to see the Batcave, discover Batman's identity and Robin makes some jokes. Batman is too ashamed of Batgirl to EVER allow her to meet any of his Justice League friends (aside for J'onn). They team up and beat the villain. Roll credits.
Formula isn't always bad. If you do it efficiently, have some twists, and some good animation/action, it can still work. The problem is that using the SAME formula for what appears to be half a season at least so far is waring thin. The Flash is one of DC's best known heroes and a founding JLA'er, but his episode with THE BATMAN was the worst episode of the season thus far, making some of the generic bits in "The Batman/Superman Story" look like Timmverse brillance. It isn't as poor as anything from the first season or any of the duds from Seasons 2-3, mind you. But next to Season 4 or some of the gem episodes from Season 2 and 3, and it's mediocrity is obvious.
The plot of the episode: Mirror Master and his lady sidekick (would she be called Mirror Mistress?) blow into Gotham city by creating copies of Batman, Robin, and later The Flash to commit some robberies of lenses. Eventually the real Flash shows up and the trio have to unite to keep this new fiend from looting all of Gotham. Okay, not looting Gotham, but kidnapping it's richest citizens for ransom, but aside for that it really is no different from Count Vertigo a few weeks ago. But, really, this episode was essentially the same as the Green Arrow one, which was handled a lot better.
The lone original bit was the fact that Mirror Master was framing the Dynamic Duo as well as Flash for his robberies, which included assaulting security guards, and NOTHING is done with it. I hate wasted potential. Imagine how much more rivitting has Batman, Robin, & the Flash had to contend with a hostile media or even some SWAT teams gathering? It at least would have added some sort of unique detail. THE BATMAN has had a library of wasted potential out of some episodes' details, and this one adds to that pile. Batman figuring out these dupes were "mirror reverses" was cool, but aside for that, nothing too special.
Charlie Schlatter gets to reprise his role as The Flash after voicing him way back in 1997 in the Season 2 SUPERMAN: THE ANIMATED SERIES episode "Speed Demons". Frankly, I can see why Micheal Rosenbaum was recast for JLU, because he is much better in the role. Rosenbaum can crack jokes and be a clown when he has to, but he also can have an air of seriousness and experience when he wants to. Schlatter doesn't, or at least didn't have much chance to here. The Flash was too much of a looney tune, acting almost like a mildly toned down Freakazoid. He had his speed powers and vibrating, cyclone bits, but he acted a bit immature and I had difficulty believing he'd actually battled Mirror Master before from how he acted, much less beaten him before. I can take Robin acting a bit like a dweeb, he's still in junior high. But The Flash? He came off more like KID FLASH at best. Plus, when Batman tells him that Mirror Master is in Gotham, Flash is genuinely surprised. If he wasn't tracking the foe, why the hell did he invade the Batcave at random!? Maybe the writers were trying to make Flash seem quirky, but it backfired a bit.
Plus, the episode has an unintentionally hilarious and homoerotic line when Robin gushes to Batman as they race into the Batmobile, "Let's do some grinding of our own!" Hoo-boy. Episodes like this make me REALLY miss Yin and the subtle romantic tension she had with Bats.
Mirror Master's voice wasn't too bad, a bit generic but that isn't strange on THE BATMAN. His design, especially the mask, was too stuck in the 90's period of "half masks". The episode had some decent action, but we've seen a few "mirror matches" from THE BATMAN before, especially after two Clayfaces, so it wasn't anything too terrific. Naturally, Batman picks Mirror Master's pocket and saves the day. Only Green Arrow had the nerve to almost upstage Batman on his own show.
I don't mind that Batman isn't borderline paranoid here, but the problem is that things are kept so light that he all but resembles the "Costumed Cop" of the 50's and 60's. An attempt for a lighter Batman for a new generation isn't bad, but pretending that the 80's innovations never happened is starting to go too far.
If The Flash couldn't even be handled well, I am not having hopes for lower level hero team-ups like Green Lantern and Hawkman. But hopefully the writers will have realized how generic things are and mixed things up. How about having a Leaguer call Batman for help and he goes to an outside city for once? Y'know, something?
If not, though, then it is a good thing this is the last season, and THE BATMAN can exit the stage with some of the dignity it gained last season intact.
