You apparently missed the memo a few years back that acronyms in America no longer have any grounding in reality.
Case in point: KFC = KFC there are no longer any words properly associated with this restaurant franchise...and AMC is no more or less misleading than MTV, which stopped featuring any M a long time ago in favor of over-gelled, orangish jersey-ites.
With AMC you just have to engage your suspension of disbelief while you are surfing through the channel guide. This makes everything easier to swallow.
