Narrative:

We were cleared for visual approach to the left parallel runway about 10 miles out on a 90 degree dogleg. We turned to create a shallow intercept angle aiming about 1 mile prior to the final approach fix. We began descent to 3000 feet at about 800 fpm. We received a traffic caution. The first officer looked outside and verified visual contact as I (pilot flying) disconnected the autopilot and turned away from the traffic. We were about a quarter mile from the localizer centerline. The other aircraft seemed to have gone through their localizer course. I turned as a precaution to prevent possible close contact. The first officer stated the other aircraft had finally started a hard right turn back to their approach course. We received a RA monitor vertical speed command. I continued as I was flying as it was a descent rate less than the aircraft was warning therefore it was in compliance. We received clear of conflict. The first officer notified ATC. We were right about the FAF and elected to continue the visual approach as we were still safely configuring and aligned for the runway at this point. We were able to continue to a safe and normal landing. I believe ATC cleared us possibly a little early for the approach. It seemed we should have been staggered with the other traffic rather than in a position to approach directly beside it.
