Based on your dislikes...you may just want to watch Mass Effect 1 game play that focuses on just the story. ME2 and 3 smooth have better mechanics with both combat and exploring.

Narrative???!!!! IMO (ME is my favorite video game franchise) the story and choices and character development is on par with any high production TV show. They nailed the narative.

Asthetic sounds like it should be up your ally! Plenty of slick designs but nothing not totally unbelievable. The Normandy for example, it is a gorgeous spaceship but has plenty of realistic features.

I'd say you would enjoy playing them. Just be mindful of the slow pace of ME1
