Firstly, I want to keep the whole nepotism factor aside and look at coolie no.1 from the point of view of a movie enthusiast.
I'm sorry to say that this movie was indeed a huge disappointment. The dialogues were so cringe-worthy and the storyline didn't make up for it either. And please...I don't even wanna get started on the screenplay!. I felt like the movie was a complete waste of time. I'm not going to hold it against any of the actors cause I have seen them perform really well in other movies, for example, Varun in Badlapur, Sara in Kedarnath, Paresh Rawal in OMG (well, I'm sure you get my point here). My opinion is about this movie alone.
Overall, this movie was a huge disappointment. So, if you want to watch something worthwhile, this movie isn't the best option.
