Batman Redux Ad Nauseum

This morning, I watched the most recent Batman vs. Superman trailer, and I was suitably impressed. I actually felt like I should watch “Man of Steel,” which I deliberately skipped, to prepare for this one. If the full feature is structured as well as the trailer, it has the hallmarks of a good story.

But.

There are a couple of cuts in the trailer that made me roll my eyes. At about two and a half minutes in, we see young Bruce Wayne reacting to his parents’ murders, and then what looks like their funeral. Now, maybe in the full feature, these scenes are just a flashback, but even so, why waste screen time on it? Is there anyone who would go see this movie who DOESN’T know Batman’s origin?
