I don't really know if you have to watch these shows to watch the new movies coming out and I'm sure if you do 90% of the audience who didn't watch the disney+ shows will be terribly confused. Anyways the show reminds of another Marvel show The Defenders. Season is painfully average except for one episode which makes you finish the show wanting more like that episode. For this show that episode is the fourth episode. The show if needed for the movies is basically a mandatory watch for the mcu.

TLDR painfully average but is most likely necessary for new mcu movies.

7-10 Average.
