I can't tell if this is good or bad acting but she's just constantly emoting and expressing consternation at something, and it generates low-level stress in the viewer whenever she's on the screen. Watching her carry an entire Netflix show is grueling.
I know but she still gets cast in lead roles because she's supposed to be the Gen X Meryl Streep or something iirc. You can see every wrinkle in Dolby Vision on The Beast in Me brought to you by Netflix.
