The thing about Batman Earth One, as I have stated over in the thread itself, is that we aren't really seeing a new story.
Batman taking his first, often clumsy steps as a crimefighter and finding it difficult at first? Batman testing and developing his techniques, methods and gear as he goes?
The only way, then, for this to be a worthwhile endevour is for it to be a superior work to Year 1. Not impossible, but highly unlikely. Also, the way I understand it at least, these interpretations are supposed to be different, but still true to the core of the characters. Spoiled brat Bruce Wayne? I don't think so.
Bruce wayne, at his very core, is an exceedingly good human being.
Now, if the case is that it doesn't need to be true to the core of the character, the a spoiled brat Bruce would be justified. However, it's not something i'm interested in. If you can't, or would rather not, write Bruce Wayne..... then don't.
