A long line of bastards

Supervillain Thanos wants to capture all the infinity stones of the universe, so he can be the supreme leader, get total control and kill the inhabitants as he pleases. The superheroes of the galaxy must gather up, join forces to stop this madman. It's a very good movie, possibly the best of its genre, altho I wish they'd ease off the pedal a little and wouldn't produce these Marvel flicks at such a frantic pace because thrills of excitement may die out of oversupply.
