To see how LOW is the batman detective bar....
BATMAN HAD TO ASK AMANDA WALLER TO HELP IDENTIFY WHO THE FLASH AND AQUAMAN WAS
He is a DISGRACE for comic/tas batman
You don't know that. Batman deduced Lex was searching for Kryptonite and preparing to smuggle it. He tracked down the Russian to an underground fight. He figured out where Diana would be with only a glimpse at the gala. He knows were the Sword of Alexander is when even a curator doesn't. He can crack military encryption. From Suicide Squad, we learn that Belle Reve is a black site and we know Lex is at Belle Reve based on the should patches of the guards. Waller describes Belle Reve as a thrown away hole. Yet, Batman finds Lex and infiltrates this black site to get face to face with Lex.
Do you really think he needed any "help" identifying Flash or Aquaman?
If this is low-bar discount-detective Batman, how would he even know Waller knows anything? This is a Batman that's developed intelligence network that covers all of the above- Lex's scientist soliciting locals, underground fights, smuggled weapons, and government black sites. It's disgraceful to pretend that's nothing.
Batman simply wants to know what Waller knows.
If you think it was solely about Flash or Aquaman, why is the first page we see Enchantress? Waller asks him "Why Mr. Wayne?" and he answers, "I just like to make friends." His way of saying, "They're mine and off limits." If they don't have this tête-à-tête, Batman happily recruits Flash and two months later, Waller is kicking down Barry's door at 4AM looking to plant a nano-explosive in his brain-stem. This was not about, "Please Amanda, help me!" How absurd! Waller is ASKING for Bruce's protection and Bruce ends the scene with a threat, "Shut it down." Just because
you can't deduce what's going on doesn't mean the movies didn't show Batman is capable of significant deduction.
