Narrative:

Weather was moving through the airspace. Two sectors were combined feeding me at the finals sector working staggered finals. The center was feeding arrival aircraft all over the place that should have been put on a different arrival route. The sector feeding me was overloaded with deviating aircraft; and this resulted in a wildly out of control and unsafe operation.we tried to get the final into simultaneous approaches and split of the finals sector. The feeder's aircraft were coming in from the southeast in an absolutely unsafe feed from the center which resulted in a possible loss of separation on final between a straight in and an aircraft from the southeast.better communication between the supervisor and traffic management was needed. The traffic management unit (tmu) supervisor dropped the ball and allowed an unsafe situation to occur. Tmu should have been paying attention to our operation and put the center on a different arrival route. Supervisors should have put the center in holding when this didn't happen.
