There's been a real dearth of action shows with female leads for a while *mourns T:SCC*, so I'm excited to see one getting on the air at all. The last Bionic Woman remake taught me not to get my hopes up too high in advance, though.

I know the actual answer (the CW has been doing so badly that it will keep almost anything around), but still. One Tree Hill is on Season 8! Smallville is on Season 10! Even Supernatural has kind of defied the odds by sticking around for six years.
