Since marketing for this show seems to be nearly non-existent, here is a heads up.

As this is about an entirely new character within the MCU (Simon Williams also known as Wonder Man), odds are you can watch it without having seen anything else from the MCU. Two returning characters are confirmed: Trevor Slattery (the actor posing as the Mandarin in Iron Man 3 , who was also in Shangchi ) and Agent Cleary (who appeared in Spiderman No Way Home and Ms Marvel).
