The show is at it's best when all the girls are working. I love work dramas--especially with something as stressful and interesting as the making of a terrible anime. When that is the focus of the show (especially early on) it shines. It's a pretty harsh critique of anime production in general, but the cynicism pays off in the form of good humor. The characters are generally enjoyable, especially the main character. Chitose is arrogant and lazy and not particularly talented, but generally good natured. She seems to be one of those people who you just love watching in a show but would hate to work with. The side characters are mostly a little bland, with a cute bit in the middle that expands on two of them.
The show does tend to slow down and lag for a while in the middle (especially that part I mentioned earlier that develops the side characters), but other than that, I only have one real complaint about this show. I don't like how they handled Chitose's character development. I'll keep it spoiler free, but suffice it to say that they developed Chitose's character too quickly and without her facing much adversity, placing the focus on what I think are the wrong ideas and values. But that's pretty much it for complaints.
The show isn't stand-out good. It's no contender for show of the year. But it's pretty blandly decent with a few good laughs. If you wanted to give it a try, I wouldn't discourage you.
