6. Guardians of the Galaxy Vol.2
The sequel to Guardians of the Galaxy might be a great space adventure and it made even more than the first one. Vol 2 managed to bring in $863 Million at a production budget of $200 Million.
The sequel to Guardians Vol. 1 took the pieces left and turn them into something amazing. The original Guardians added more members (Yondu, Mantis) to help them take down a Celestial – Ego The Living Planet. It was bigger, better and more exciting.
