Flight safety was very poor indeed. Very few people paid any attention at all to the safety demonstration - flight crew could have done much more to get and keep attention to this important advice. Many passengers where just laughing and joking around taking selfies! - not good at all if there was an accident. Further two separate passengers got up during landing procedure to go to the toilet!! I feel the flight crew as nice as they were could have been more 'forcible' after all the plane was only 2/3 full.
