The Marvel franchise needed a couple of new heroes, so in “Guardians Of The Galaxy” we follow a bunch of space criminals who have to work together. Initially to break out of prison, but then to save the universe.
The only link to the “Marvel Cinematic Universe” appears to be that the globe that everybody is after, contains one of the “infinity stones”. Needless to say that some bad guy wants that globe to destroy the universe and the group of new heroes thinks that is a bad idea.
We have a ‘normal man’, a green woman, a rodent with a walking tree and a hulk type brute. Strange characters reminding a bit of Star Wars fill the screen. There is of course action, but all very ‘spacey’. Nothing too great.
