Excellent issue, excellent use of S.Thing, but I have to admit the ending was a tad discordant with me (but fits with the King/Snyder conception of Batman). This does take place after The Button* and Bruce was probably unnerved by just witnessing a murder, but Bruce's reaction at the end did come off a bit as "I'm a crying baby who you need to pacify and lullaby."
Morrison said a good deal in interviews about how Bruce has studied all these exotic and sage arts and religions and you'd think Bruce would carry them with him and display more some of those disciplines, more a calm and ability for stoicism and zen, given all the wonderful different perspectives he was trained in.
As far continuity:
*By the way, where does this issue happen in relation to the ending of Flash #22? Between its pages perhaps? Actually, it really might just take place right after. I think everything is suggesting that spoilers:end of spoilers
Bruce didn't make some decision to stop being Batman right then and there at the end of Flash #22.
