I don't get it.
The animation was average. A bit below average actually. It was like an old Hanna-Barbera cartoon, where only the lips move and they kept everything else still to save on animation costs. And even with that the lip synch seemed a bit off in sports. The whole "batman" thing just wasn't very funny. Maybe to a kid it would be funny, but not for an adult viewer. It was such a slow plodding effort just to get to the punchline, which was OK though somewhat predictable. That saved the entire flash from being a well-made spam. You obviously have drawing skills. I'd suggest for the next flash that you work to improve your scripting, or collaborate with someone to help improve and flesh out your ideas.
