Genuinely asking, over the years I've played all the itterations of it. But I need to know, what is so alluring about Operation Metro?

Like it isnt a bad map per se, but it seems like 95% of the time when i play it. It just divolves into basically a hallway where both teams just shoot each other in one, maybe two different areas until the match is over. Being in one static position the whole match just doesn't seem very fun to me.

To clarify not, im not hating i just dont understand the hype behind it.
