First of all, it really depends on the genre of the movie and depending on that you can decide whether to watch it or not.
According to me, it satisfies the need of comedy and drama.
You probably may had have heard negative reviews on this movie just because of the fact that mouthshut pays more on negative reviews.But trust me guys its not like that.
The main point in this movie is you must avoid confusion between Charan and Karan twi s which became thier cousins due to accident of thier parents when they were young while travelling via road.
So, both the brothers were care taken by thier mothers brother MAMA ( Anil Kapoor ) . But soon he realised that it is impossible to handle both of them so he sends one of the brothers ( Charan ) to punjab with Bua ji and one of the brother ( Karan ) in london with his sister of Anil Kapoor ( MAMA) .
So, the whole plot of the story revolves around both Karan and Charan have thier Girlfriends but thier families started to find girls for them for getting them married but niether of them wanted to get married with someone else as they already had thier girlfriends but to rescue their MAMA helps them and gets both of them rescued to not get married but later everything gets sorted out in between with blend of Drama and Comedy.
Verdict - At a point , movoe is predictable but its not totally the same of what you think.You may hate it or love it but here comes the point, if you like to eatch comedy movies then its a good movie to watch atleast once.
THANK YOU !
