Ah, but declaring on behalf of the line's users that actually, buses were enough for them until such time as a full subway was feasible is quite a bit more than merely criticizing the line.
Funnily enough, I have the exact same opinion of unimaginative people like you who have no idea how transit works in other parts of the world and believe that subways are the only valid form of transit, and insist on hogging all the capital cost dollars on building a few highly limited megalomaniacal transit projects that deliver far less upgraded transit per km than a network of surface LRTs ever would. I'm sure all the people who would be stuck riding buses in mixed traffic under your transit vision because there isn't enough money to go around and upgrade their line are absolutely thrilled with you.
