Complex Analysis and graduate admissions

[Löb'sTheorem]

I recall seeing that having taken a graduate course in complex analysis as an undergraduate and done well is a particularly good indicator that you will do well in a graduate program and sticks out; more so than other graduate courses. I'm not sure if this is true, and it doesn't totally seem sensible to me, so can anyone tell me whether this is or is not the case?

I've never even heard of that before. I'd imagine what sticks out more is doing well in grad courses related to your intended field.
