Rogoway's Reviews: First Man Is A Stunningly Raw Tale Of Rockets And Reality:

"First Man isn't primarily about space. It's about a person who ended up there.
It's a stripped down, raw story that serves as a reminder that not all heroes are
full of one-liners, love the limelight, or are without heavy imperfection and deep
emotional scars.

Let's get to what many of you are wondering most about this film first—the action
and its level of realism. This is a unique film in that it largely omits the
technology out of flight sequences, but instead, it dials up the drama and
suspense to the absolute max. On that level alone, many of the scenes are a
cinematic triumph—you feel claustrophobic 'in' the capsules and are uncomfortably
faced with the seemingly narrow margins for success of key maneuvers, but there is
also something lost in the simplicity of it all."
