You answered your own question. A lot of people have issue with a full priced game being as short as this reportedly is, with little reason to replay the game except for some collectibles (no NG+, very linear). It's a value thing.
But value is not measured only in length and re-playability. I like open world game like the next guy but it should not close the market for close-focus, intense short game that are often presenting things organically and with minimal "tricks" to make it last.
This is just a different part of the market. The Order never pretended to be something else and no-one is forced to purchase it. If it's not what someone is looking for, by all mean give it a pass, but don't force your views on others that are actually interested in that kind of experience.
