After watching it for the second time, that too in a multiplex, along with the family, i viewed it with a critic’s eye and surprisingly did found few noteworthy misses. Although not intentional, the director and his team did play some fouls along the way. I found few, you may add yours.
1. Director explaining Raju & Farhan about the Income of their respective family. He rubs the zeroes out. A dot remains on the board when camera leaves him. The same dot is extinct when the camera returns.
2. The name Raju Rastogi sounds unrealistic. Rastogi surnames are usually carried by Parsis. Nor did he had a Parsi accent neither his family seemed so.
3. Suhas runs into his weeding with a night-coat. He suddenly disappears while Raju flies away with Pia.
4. Farhan drops the cover of Shyamaldas Chachad's astiya into the flush. The same is seen atop when Raju and Farhan leave the place. Loosing contacts between the 3 Idiots felt unreasoned. Nor was there any rift nor did any profound calamity. (Only thing that might have made them apart would be for covering the identity of Phunshuk Wangadu.)
5. Millimeter gives back Pia her helmet when they reach the school in Laddakh. The Helmet is scuffed upto at the corners. But the helmet she wears while riding the scooter later is brand new and shines like a red cherry.
(The critic in me is only for comparing the quality of 3 Idiots with the Hollywood directed movie and not for the very purpose of criticising – The 4th Idiot)
