Got to agree. Good news if you want to go to Didsbury and Chorlton or dungas going to Old Trafford, but of little use if you want to go to the City Centre - far quicker by proper train.
It would be better if they went and spent more and extended it through Tiviot Dale, Portwood, Bredbury to Romiley, Woodley and Hyde - would alleviate some of those journeys into Stockport from the east side of town.
