Firstly you have to wonder about a TV series where all the characters call the lead by the incorrect way. Myfanwy is an old Welsh name pronounced me-van-wee, not as they say Miffany, surely someone should have pointed this out.
As for the cast, well they are going through the motions, nothing more. From the first few minutes in you dislike the lead, wishy-washy, bland etc. To be honest if you want something different from the usual superhero, anti-superhero you're in the wrong place, it ain't Legion. Basically it's the same as all the other banal sci-fi teen stuff, not as bad as 'The 100', but daft. Six stone slight women beating the hell out of man three times their weight, woman loses her mind, but leaves clues that anyone could find etc. The script is laughable in places, you wonder what research was ever undertaken, crime scene, pathology wasn't included in the research that's for sure.
If you like your sci-fi with pretty people, characterless, pointless sex scenes, swearing for the sake of it, poor acting and a plot more open than a mountain range then you'll enjoy. If you prefer TV series like 'The Expanse', 'Discovery', 'Legion', 'Westworld', then avoid.
