Batman + Punisher with a dash of Bond...
Your version of batman is nothing more than a Batman who massacre's his enemies Punisher style. What you have done is taking what Batman is best known for, his stealth and mystery, and warped it into a mindless action flick.
The story was simple: Robbery, bat signal, Batman Kills enemies, Batman bangs Catwomen. During action sequences, all I could think of was Punisher in the Batman costume. And I will add a touch of Bond because of that last scene.
Putting aside the story, the movie was well animated. Those brief seconds of batman flying through the movie and eclipsing the moon really made me really appreciate the animation more. Those signature scenes is where most of the "style" resides.
The sound was well mixed and fit in place well.
Overall, this flick doesn't really fit Batman too well. Perhaps its best to continue a story like this with a Superhero creation of your own.
