Masti is one of the most enjoyable Indian comedies released since 'Dil Chatah Hai', and is a must see for Bollywood movie goers who enjoy comedies and are open minded.
The start of the movie is superb, with effortless acting and great comic timing shown by the main actors; the first 1/3 of the movie deserves a 10/10. Later however, the film tries to take itself too seriously and fails in some respects; Ajay Devgan showed dry acting for a very dry role, 'I hate crime, and i hate criminals'; please...
However the dialog remains enjoyable throughout, and the ending seems to tie things up well. The songs are also fun and stay within the plot of the film; i.e. no flying off to different locations around the world changing clothes every few lines.
As for the girls, Amrita Rao is the Queen of Cute; both she and Lara seem to be the only girls with acting and dancing abilities. However the rest may something to be desired in different departments.
All round, this movie is packed full of laughs and Masti, which all make up for the lack of plot, and thus Masti is a must see if you enjoy a good laugh.
