I agree with previous reviewer, this show is rather lackluster. The first two seasons were decent but it just went downhill from there. Also due to watching all of the series all at once, the glaring use of stock footage (or whatever it's called) is very annoying. Watching the same random figures walking around the office is really not that necessary in my opinion and gives the show a cheapness about it.
Also the way they tell each other things is also a little grating! Especially personal issues. But that is just a minor observation.
Billie is a decent character. Rob is a little boring to watch. He really has no depth. Vivienne by far carries the show and the boss is just useless!! Not sure if it will have any further seasons but I will probably not be watching unless ACORN has nothing good on at the time which happens every now and then.
