It all starts when Thor's adopted brother Loki (Tom Hiddleston) causes havoc on earth in order to rule the human race. Loki has left Asgard and now wants to ref ashion earth as his kingdom and humans as his slaves. Loki intends to steal a cu be (energy-source) called the Teseract which would help him and other vicious al iens to wage a war against humans. It is now upto the superheroes/super skilled warriors to get together and save t he Earth. But will the 'eccentric freaks' comprising of tech genius, good guy but cocky Ir on Man (Robert Downey Jr), Russian spy Black Widow (Scarlett Johansson), the man with anger management issues Hulk (Mark Ruffalo), righteous & man of morals Cap tain America (Chris Evans), master archer Hawkeye (Jeremy Renner) and hammer-wie lding god Thor (Chris Hemsworth) put aside their apprehensions, ego, controversi al past to fight alongside each other and against the aliens? The Avengers' build-up is a tad slow as the initial formation of the super-hero force takes time but once that's done; the film grips you with its fast-paced ac tion, sleek one-liners, engaging banter and endearing humour throughout. When yo u are not clapping after every stunt scene, you are awed by the greatness and my stique of the mighty superheroes like a child! Director-Screenplay writer Joss Whedon does the implausible task of accumulating the superheroes for a common cause superbly. The script lets every character ha ve its moments except for Hawkeye who gets the least significance. Jeremy Renner seems wasted. Barring him, rest all get equal opportunities to showcase their s uper-powers. Robert Downey Jr's magnetic personality, sarcasm, sharp wit and distinct portray al of Iron Man manage to hold the film together. As Tony Stark, RDJ infuses that much needed spark and life into the movie with his superb one-liners. When a ri ghteous capt America questions flamboyant Stark's heroic abilities saying "Take off that armour and what are you?" Stark mockingly replies, "Genius, billionaire , playboy, philanthropist." Stark is also seen in his plush New York apartment i n this movie and not California. Mark Ruffalo playing The Hulk is another reason you enjoy The Avengers thoroughl y. Watch out for Hulk's interaction with Loki, you'll die laughing! It is one of the best scenes in the movie. Ironically, the big guy tickles your funny bone e very time he loses his temper. Mark Ruffalo plays the role with absolute ease an d conviction. You don't think of Edward Norton or Eric Bana even once. Tom Hiddleston as the wanabe tyrant (Loki) is impressive too. Chris Evans plays sober well as the righteous Capt America. Chris Hemsworth as Thor makes his pres ence felt. The Avengers does not fall short of anything. Stunts, story, performances, humou r...the film has it all and just in the right proportion. Humour is in abundance but no way does it make the film spoof-like. The banter between the superheroes is as interesting as their fight with the aliens. Joss Whedon leaves you emotio nally invested in the movie. You feel for the characters, which makes the film a roller coaster ride you don't want to miss out on! It's a feel-good fun film..
