I'm gonna say the Czech republic.
I haven't ever been there, but pretty much 100% of all Czech beer imports are boring lagers.
If I'm gonna drink a lager, I may as well grab a Bud or Miller, because while they may not have the most exciting flavor, they are priced fairly and they are at least made with decent quality ingredients and they are very consistent.
That said, I'll take pretty much any Ale over any lager any day.
