Well, let's preface this by saying I'm a 71 year old lady, retired, often hurting and watch a LOT of television, good and bad.
Inventing Anna is definitely a "Chick Flick." My BF would have blown it off before the 1st Episode was finished. He also happens to be of Austrian ( i.e. German speaking) parents. I have seen this actress is a couple of other things and she does better as a Hillbilly American loser. Her accent was just BAD and someone in the production SHOULD HAVE NOTICED this ! She did not sound AT ALL like a native German speaker ! It speaks to the fact that so many of our countrymen have never been out of the country or learned a second language.
That said, I was entertained on & off but did I think ALL of the people the character defrauded in the Series were STUPID. But no dumber than I was watching it to it's completion.
