I hate to be a huge downer here, but regarding the whole action series and the female character being the lead actor and so on...well, there actually is a trend like that- you have series like She-ra which involves an action cartoon and a lead character. Know what that has in common with this? Its essentially a female version of a male character- in the case of She-ra, He-man came first, was popular, and got this as a spin-off series. And now here we have a female version of Avatar....I feel awful saying this, but I kinda feel like this isn't particularly groundbreaking. The devil's advocate in me wants to take on an ultra feminist stance and point out that- yes, you aren't subscribing to the conventional wisdom that you can't have an action series led by a female character. You are subscribing to the conventional wisdom that you can't have an action series unless their female character has had a male character version of herself test the waters first and prove its safe and viable for marketing.
