Sea the Airline quality website and the same complaint is repeated again and again.
From a recent trip to DXBI can tell you that the aisles are narrow, and the seats unbelievably tight. I was fortunate that with my wife who is small and 6 year old daughter in the middle of a row of 3 it didnt matter my shoulders being in the other seat.
However the argument that broke out in the row in front due to the guy and wife taking up the aisle seats and a lady being crushed in the middle seat who thought it bad form husband and wife wouldnt sit next to each to other suggests that others found it a problem.
The entertainment was excellent, leg room not bad, food ok - but I will never fly them again in the back until they go to 9 across.
