Overall, the series was going well until the second last episode. They have provided some mystery to the Graviks character and shown him to be quite powerful.
Towards the end of season 5, Fury seems to have little no chance to turn it around with so many characters dying by his side.
But the last episode, totally ruined the enigma. They shouldn't just keep killing off the characters and show one to become the most powerful. There had to be some mystery left by the end of the show, that was marvels' style, not just come up with solution to the problem in one episode. The five episode build up ended in 1 episode, makes it more like a bollywood movie and not Marvel.
They could have kept Gravik alive, but leaving or hidden for now and the threat could have been either remaining or maybe change of hearts. He couldn't just die just like that. Also, the powers given towards the end are hilarious. Should have kept some logical sense but added a surprise element to it.
Disappointed by marvel phase 4.
