I'm not going to panic here. Larson could very well settle into the role with the Russos directing her in Endgame, and we'll have nothing to worry about.

I didn't really "get" Hemsworth as Thor until Ragnarok, and Cumberbatch's Stephen Strange didn't level up to a top-tier MCU character until Infinity War. ('Kat, you saw the look in my eyes when Strange battled Thanos at the end. It was like a childhood dream coming true.)

So, give the Oscar winning actress some time. She'll get this.
