You think there haven't been efforts to improve, both by the Wayne family in general and Bruce specifically? Not only does the medium necessitate that things be available to fix constantly, but in-universe there's about ten secret societies, a dozen ancient curses, and probably a demi-god or two whose express purpose seems to be to keep Gotham as miserable as possible.
Real life isn't even as easy as "throw money at it to make it better", much less a universe that is predicated on needing something to fix on a monthly basis or they lose revenue.
I think it's easier to find the weird stuff these days. Back then you'd basically have to be a part of a particular scene, or have someone i produce it to you. Otherwise you had whatever top 50 radio stations were in your area. Speaking of formulaic...
Ah, the usual "I saw that scene from Snyder's BatmanVSuperman so I feel I can authoritatively speak to the entire character"
He has gone through probably hundreds of writers at this point, all with their own interpretations. But generally, when they stick to the "I hate killing and guns" type, he's not breaking mooks over his knee Bane style. It's not universal, and some of the writing is just bad. But that doesn't define the character anywhere except the minds of people who just want something to shit on.
It's not so much whether or not he knows it, so much as how much he cares. He knows what he says will get his base riled up, and that's what he likes. It strokes his ego and gives him more power.
I believe the temperatures within the chart are "feels like" temperatures rather than absolute temperatures. The X axis shows absolute values (what would likely show on the thermostat).
At OPs original temperature (91°F) the danger zone would be around 60-70% and higher. At OPs last updated temperature (94°F), the danger zone would be 55% or higher.
Ah, so 3.0 is fine if your internet still sucks. Got it.
