Microcarbonated... okay whatever that means, the bubbles do seem smallish and the beer a little smoother than most. The beer is a light gold colour in a glass, a little malty and barely bitter. Overall fairly bland but refreshing. It seems like an upgraded version of a light beer: a slightly better kind of bland with slightly more alcohol.
Molson M is a good enough lager and when I think of just how bad some other international lagers are, I think Molson is justified in using the distinction (slogan?) of "premium lager".
