Potential
You've got potential. There are a few issues I have with it though. For one no preloader, not really a big deal but would help with people that have slower connections. My main issue is that Batman wouldn't kill. Yeah he didn't "save" Ra's Al Ghul in Batman Begins and that bothered me, but it's Ra's he doesn't really die because of the Lazarus Pit, so I expect him to come back. Other than that man, great job.
