The FIVE star is given only on the following assumptions
We all have seen great films from Bruce and know his level of commitment. His present mental/medical condition is also known to all.. And it shows on screen too. I assume this film was done more to support him or out of respect for him. Just extending a hand shake ro show that his friends still care for him..
Other than that, I must say its a total waste of time, money and energy. Your time and money have better purppse and use..
