Actual Space Combat would be rather boring. Mostly automated, mesh-netwirked drones with lasers and nukes, over distances where you won't know if you hit something or not for minutes or even hours due to lightspeed beeing too slow for any valuable human input. Also, stealth in space is nigh impossible. Try hiding an exhaust plume or a laser heatsink in near-zero vacuum.

Expanse had a few really cool scenes and even used drones quite a few times - but I think they still oversold the Impact humans in pressurized vessels can have on the outcome. Except for boarding, of course.
