I don't know why most of the audience is criticizing the film. Housefull franchise was always a no brainier watch. Housefull 1 was hilarious, 2nd was just okay, I did not even dare to watch the 3rd.
But 4th was between 1st and 2nd. A story based on reincarnation (like ek paheli leela), with some PJs making up for the comedy (as the franchise always had been). Even though they hopelessly copied bala from the dictator, if you have watched it and leave the anger behind, you will enjoy this in nostalgia. If you keep an adamant mindset and watch this movie, you are not going to enjoy it. But if you watch it how the director wants you to watch it, you are definitely gonna enjoy it.
I agree that they could have put more effort in the screenplay which is the main reason I am giving this movie a 3.5 star rating.
