Ad Astra is a space drama which I enjoyed but wouldn’t sit through again.
However, I prefer Interstellar and Gravity to Ad Astra if we are comparing similar films. Space madness is introduced in Interstellar, and it is an element in the narrative here. It seems the longer you are in space you might become crazy. Brad Pitt and Tommy Lee Jones characters had shades of that, but it didn’t stop them from trying to achieve their respective missions.
Overall, the film feels long and boring at times. It can be trimmed. Good movie, but not great.
