I think what everyone has said is overall...true. So far, the C919 is not selling well. 165 orders pales in comparison to the A320neo, 737max..etc. Not to mention, many of those orders are options and virtually all from China's state controlled airlines who are being pressured to buy chinese.
That said, personally, i do not think the C919 will be a "bad" plane. The reason it isn't getting the orders is the uncertainty. The ARJ-21 is over 5 years behind schedule, yet that project is not nearly as complex as C919. Airlines don't want to order the first Chinese jet, a jet that may not be delivered until 2020. They want something from a company with a proven track record, Boeing or Airbus.
The thing is, China is in this for the long term. The C919 may not make a dime of profits, but the C929 will. It will take China a long time to pose a serious threat to the airbus/boeing duopoly.
