In better hands - scripting, directing and casting of main character - this would have been a winner of a movie based on a real-to-life mathematical genius.

As it is, the whole thing is simply trite, contrived and a whole waste of a good opportunity. Right up front, the use of near standard English by the Indian cast who were supposed to be from the "abject poverty" of Madras is downright unbelievable and ridiculous.

The script doesn't know what it wants to focus on - is it about an Indian displaced in England? Is it about the genius of the man? Is it about the tribulations of leaving your young wife and family to go abroad? Is it about another important leap of mankind in the area of mathematics? Is it about the relationship between a student and his mentor? It is all over the place and at the same time pointless and trite.

Jeremy Irons is superb and is the only key redeeming feature of the whole movie. Cinematography is colour-by-numbers, but good enough. Apart from the mundane meandering scripting, Dev Patel is a total miscast. He is simply a one-dimensional school play actor who simply does not at all have the talent to take on the range a proper lead sorely requires. He is just playing himself in all the movies he has done - same doe-eyed expression, same hesitating mannerisms, same scuttling around, same intonation, just same himself - he does not at all inhabit this very important lead character, and his amateurism is just a constant sore annoyance throughout the movie.

This movie is a dis-service to Srinivasa Ramanujan. It doesn't give any insight into his genius nor a sense of his highly unique and compelling short life.

Watch it with little expectations, and it may be mildly entertaining, but never interesting, and certainly never compelling.
