Not much of the story or character development, but the 70s music and the humour keep the movie interesting,

Rating: 7/10 (25 November 2014)

Quite a fresh and humorous origin story for a group of vigilantes-turned-heroes. The plot is quite predictable and there's no character development at all, but the movie doesn't take itself too seriously at any moment and it's aware of it, and that certainly works in its favour. The 70s music comeback for a superhero film was quite a surprise, and it worked wonders for the storytelling. The spectacular sets and the brilliant special effects certainly add to the beauty of the film. With a little more story and character development, it would have been more memorable (like this year's other origin story, 'Big Hero 6').
The cast is well selected, especially Chris Pratt. Voice-over from Bradley Cooper as Rocket is also quite well done. Supporting roles performed by talented actors like Glenn Close, Josh Brolin, John C. Reilly and Benicio Del Toro were small but amusing. It was interesting to see Lee Pace's transformation from the Elven King Thranduil (in 'The Hobbit') to the dark and psychotic revenge-ridden villain Ronan in this one.
Hope the future parts have better storyline and character development, and hope it maintains the humour and 70s music charm of this part.
