MAN imperfect, but what's the alternative?
I think BTNH is closer to the truth than most.
MAN may not be an entirely pleasurable experience ( some terminals more than others), but if the alternative is to fly from LHR then it's no contest.
The train is undoubtedly the least stressful way to come and go - the main priority there is better services to places south of MCR, and services which cover more hours of the day/night. An 0600 flight departure or a 2200 arrival may rule out the train to and from home.
