Iv watched it.
It depends wat you think of MCU, WandaVision n superheroes shows/tv/movies in general n Sam Wilson n Bucky Barnes in particular, i think. I hv no objectivity so id say watch it. Ill try n answer any further questions as to why.
(Did you watch any Marvel Netflix, ABC, Hulu/Freeform shows n like them? If ur answer is no, maybe Falcon n Winter Soldier might not be for you. I dint watch all of them, not in the least but i tried most n stuck with some for awhile, but when things dragged on too long-i dint hv enuf time any more or interest to continue on.) Im too addicted to comics/superheroes shows to quit cold turkey tho.
I like Superman & Lois n F/WS but it'll take time to see if i like one more than the other. F/WS has higher budget for action scenes id say but idk if there will be as much in the rest of its season/episodes.
