This is a heartwarming family-based movie about three black women overcoming racism and sexism at NASA in the 1960's. The mathy-parts are stylized so anyone watching who doesn't understand the higher math being used won't be lost. Unfortunately, there's not enough of that math on-screen for those who do understand it, and the little they reference directly is hit-or-miss for accuracy. It will likely appeal more to fans of NASA, anti-racism, and John Glenn than fans of mathematics. The story is well told and the actors have some really good chemistry. It's a really good version of what you would expect to get from the trailers.
