Depends,you know....if the story is well-written and gripping and all characters have a specific role to play to add up to the plot,and are not there just for face value,then yes,i do enjoy multi-starrers.
But if you have multi-starrers just because you need to compensate for the poor storyline and direction,then a big NO.
The last multi-starrer I saw was RAAJNEETI,which boasted of a hugely talented star cast like Nana Patekar,Manoj Bajpai,Ajay Devgn,Ranbir Kapoor among others.Everyone had a definite role to play and contribute to the film and did so brilliantly.
