I have a lot to say about this film.
To start off at the obvious, Siddharth Malhotra has just the same appearance as that of Uri Boyka, if only they could imitate the fight sequences from Undpisputed II/III as well as the hairdo.
There is uncanny similarity in the whole storyline of the script to that of Warrior(2011). It goes as far as to keep the details of the last fight of the film the very same. One might think the writers of Brothers weren't very creative when it came to plagiarising smartly.
The characters are the typical overly-used archetypes. If you've watched a few Hollywood mixed martial art movies, you will tire at the unoriginality of this film.
The fight scenes do not add up for the most part. Protagonists survive the worst of blows without almost any consequences while the opposition, despite obvious strength and weight superiority find themselves struggling helplessly by the end of all fights.
Also due to it's commercial-bollywood nature, the film overly invests in emotional dilemmas even when it is, arguably, completely unnecessary.
In conclusion, it is produced by Karan Johar.
