Aamir Khan approaches acting as if he is an 'ambitious' sage on penance. Even the minutest gesticulation is broken up into detailed micro moments and enacted with panache. Such fanatic adherence to theory has helped Khan come out with flying colours in movies such as 'Lagaan', 'Dil Chahta Hai', 'Rang De Basanti', 'Taare Zameen Par', and 'Ghajini'. But it has also ended up in his overworking on the character and leaving absolutely no space for spontaneity, as was evident in the weak portrayal of Mangal Pandey. Aamir's acting is more a dissection than an exploration. The result: He is consistently good and rarely excellent.
