"Avengers: Age of Ultron" begins with a captivating scene – our favourite cast of superheroes in combat with the terrorist organisation H.Y.D.R.A., which is in possession of Loki's mighty sceptre. Director Joss Whedon's second instalment reunites the Avengers who must save the world from a psychotic android. "Age of Ultron" picks up from the climactic post-credits scene of "Captain America: The Winter Soldier". 

The plot centres on Stark and Banner's discovery of artificial intelligence in the sceptre's gem, which they use to create a seemingly sentient android, Ultron. However, things go awry when Ultron decides to wipe out humanity in order to restore world peace. Ultron goes on to create an army of robot drones equipped with lethal abilities. The Avengers must once again put aside their differences to save humanity from annihilation. This movie adds new characters to the existing cast – superhero twins Quicksilver (Aaron Taylor-Johnson) and the Scarlet Witch (Elizabeth Olsen), who harbour a murderous grudge against Stark for the death of their parents. 

The appearance of Vision (Paul Bettany), completely unexpected by millions worldwide, was a definite highlight. He had some brilliant dialogues and some awe-inspiring moments. Whedon truly outdid himself this time around – the intense action scenes, particularly the epic sequence shot in a Chittagong shipyard, should leave even the sceptics speechless. Despite the odd European accents, newcomers Olsen and Taylor-Johnson deliver a stellar performance. This instalment also brings Hawkeye (Jeremy Renner) into focus. 

Besides the obvious improvements in the soundtrack and cinematography, Whedon's success lies in making the superheroes more "human," with their relationship problems and vulnerabilities. Perhaps, this is what the previous instalments lacked: relatable character development. 

If you're looking for two hours of non-stop excitement this weekend, this should definitely be your pick.
