I Disagree. Putting Catwoman as a thieve-for-hire that works for big colectors, criminal, supervillains and etc could be really good. Each season would focus on a big story that would be build threout the episodes. Look at how it could be:
Selina Kyle is a mysterious woman. By day, she is a ordinary antiques enlister. But by night, she is Catwoman, a sexy and agile thieve that robes whatever you want... by the right price. Called by the Calculator, the criminal underworld source of information, Catwoman finds all kinds of objects for different contractors is exchange by large amounts of money, that she spends on a luxury live in Gotham City high society. But it's not that easier for Seline either. After, 90% of her operations consist of facing a deadly threat along the way for the prize. Threats that include Madam Rouge, Portex, Foice and Hammer, Blitzkrieg, Killer Crock, Clayface, The Banas, Cheetah and many others. But that's not a big deal. After all, we're not talking about some rookie. We're talking about a professional. We're talking about Selina Kyle.
