I agree with the comments, but Arshad Warsi was the best as shown from Meerut. The problem is with director who was unable to get Arshad into the Character. Everyone knows Arshad Warsi character in "Lage Raho Munna Bhai".
The film is a fun watch if you are willing to overlook its minor indulgences and the slow pace of the first half.
Jolly LLB's first half meanders a bit, featuring a clumsy 'daaru' song and a Meerut that mysteriously hides - but boy, does its second half hammer things home. With crackling scenes between Jolly versus Rajpal (Irani deadly smooth, like velvet soaked in blood) and Rajpal versus judge Tripathi (Shukla in a brilliant show, hysterically yelling, Gavel kidder-rakha Ha?!", thundering at Rajpal, "Sit down! Yeh Meara court Ha aapka club nahin!"), the action becomes electric. Drama builds as Jolly (Warsi, highly endearing and impressive) finds his voice. Jolly's astonishment at Rajpal's callousness - "Footpath sone ke liye nahin Ha" - Jolly responding, "Footpath gaudy chalane ke liye Bi nahin Ha!", mirrors the aam aadmi's bewilderment and determination to fight.
Jolly LLB works because of its bigger point - decency is for all and worth fighting for. Using bittersweet satire and plot twirls, the film shows corruption even used against the corrupt. Despite that weaker first half, this truly becomes a Jolly good show.
