Film: 'The Avengers'; Director: Joss Whedon; Actors: Robert Downey Jr., Chris Evans, Mark Fuffalo, Chris Hemsworth, Scarlett Johansson, Jeremy Renner, Tom Hiddleston, Samuel L. Jackson; Rating: ****

In a multi-hero film it is tough to do justice to each character. Imagine a multi-superhero film? Yet to the delight of movie lovers, second-time feature director Joss Whedon proves himself to be a superhero as he pulls the impossible with fun, humour and unbelievable panache in "The Avengers".

SHIELD director Nick Fury (Jackson) manages to assemble six superheroes when Loki (Hiddleston) threatens to destroy the Earth. Sadly, strong personalities don't make a good team and our superheroes fight with one another.

It is only when everything seems lost, that our superheroes realise that alone they might be lost, confused souls, but together they become something they never thought they could be - the invincible avengers.

The film is so engaging that despite some flaws, you choose to ignore these. It is witty, smart and funny, with enough comic-book humour and elements of delight for everyone from a five-year-old to an 85-year-old.

So, everything you can imagine in a film with multiple superheroes - great action, good costume, witty writing, good subplots and most of all, the superheroes fighting one another - is there in the film. It's been designed for success and this design works like a charm.

Not one character has been given extra attention while giving enough time to establish the characters of the two who don't have a separate film yet - Black Widow and Hawk Eye.

"The Avengers" thus become a surprising example of too much being put in one film, yet it working out in the end.

The long-winding, extended climax is an absolutely delight. The length is just perfect. Any shorter and it would have not done justice to the characterisations and any longer would have made it boring.

Yet, you do miss a few elements while a few others jar. A cameo by Natalie Portman (from "Thor"), like that of Gwyneth Paltrow is missed. "The Hulk", who so far we learnt couldn't control his anger, in the climax suddenly develops it becoming an adorable green monster who's as strong as he is cute. A little on how he got there, would have been better.

Tom Hiddleston as Loki, the evil but vulnerable villain outdone by his megalomania, does the best job of "acting".

"The Avengers" is a watershed film because it is a new concept. It is the culmination of the build-up of multiple films - two "Iron Man", "Hulk', "Thor" and "Captain America". This culmination also marks the beginning of a new franchisee.

Thus, this multi-hero film itself becomes a metaphor and a tribute to the literally thousands upon thousands of people who worked in unison in the films mentioned above to lead to this very satisfying end which is also a beginning.

Each one of them showed, like the film's main theme of brotherhood, what it is to work together for a common goal. Perhaps in it lies a message for real life, that our governments could do the same with the world. For even in real life, planet Earth is in desperate need of saving with no superheroes in sight.
