Great Grand Masti is the third movie in the Masti series and I must say it is the best so far. However I am certainly not suggesting that the first two movies were not as good; they were well portrayed in their own ways.
Throughout the movie there are sex related jokes and they are not vulgar or offensive in any way, in fact, they were rather funny and you can relate to them in some ways. In some parts of the movie as an audience you question "why is this happening?" or "was this necessary?" but then you’re like, "oh.i get it now!". Therefore the audience is intrigued and hooked to the jokes.
I split the movie in three parts; the introduction to their personal life, their journey to the haunted mansion and the battle between the families and the ghost. the introduction was exceptionally funny and all three of the actors -Vivek Oberoi, Aftab Shivdasani, Riteish Deshmukh- did an amazing job in portraying the characters and the comic timing was fabulous.
Personally I would highly recommend for you to watch the movie in the cinemas with your friends as you can have a laugh and a great time.
