Jen uses her for a PB and she's in a particular movie that Jen likes her from, the name of which is escaping me.
There are two reasons we're doing this show: Alexander, whom I also really love (and she's good, though I like her better when she forgets she doesn't know who she is and turns into a badass) and this is a Berlanti show (the guy who produces Arrow and Flash). It's the latter that gives me hope this might be a fun thing to watch for a whole season. So far the mystery stuff in it has been pretty interesting and they're already doing stuff with it during the second episode, so it does seem to be going somewhere.
The first episode is free on iTunes so you should check it out.
