I love Batman and I'm not alone. Batman is more beloved by the internet than a Jesus made of bacon. The concept of Batman has changed a lot over the last 75 years, but its core quality is that it adapts to the culture of which it is a part.
Batman does have some problems though. While some of these are products of their time, many are the result of concepts executed without considering of the implications. I'm no Batmanologist, but I'd like to take a few days to look at these problems.
Early Batman was built in the mold of pulp heroes; an extraordinary man who has set out to fight crime with his extraordinary abilities. Compared to later superheroes, and even many of his contemporaries, Batman has no powers. He eschews most technologies, relying wholly on the physical and mental capacities of humanity, even decades later when he's matching wits with immortal aliens boasting entire war worlds. That's not the best approach; someone who wears circus tights and a tool belt is worthless in a world where villains can punch through metal, control minds, or have guns. After all, what can a guy do that even a second-rate hero like Hawkman--who is literally a guy plus wings--can't?
