Aircraft X entered Sector 25 airspace without a hand off.Sector 64 was combined at sector 65; with myself as the D-side and Name; as the R-side. We had alerted the supervisor that things were getting out of control; about 15 minutes before it actually got busy. We were working southbound overflights who were routed into our airspace due to weather; southbound arrivals; and all 4 feeds normally as 1 feed northbound.This sector completely blew up and became unusable; with 20+ airplanes all deviating for weather; stacked on top of each other; and no course of action out of it. It was extremely surprising there were not more LoSSes (Lack of Separation Standards) or airspace deviations.The supervisor and TMU failed to recognize or take action; even after being told; that the sector was out of control. Sector complexity has changed due to the Metroplex project; and unfortunately the TMI's have not caught up with it.Erring on the side of caution; the supervisor; with the concurrence TMU should be slowing down and putting on in trail on the sector. Unfortunately; it ends up with the supervisor not taking any action; and the sector controllers caught having to clean up the mess.
ZMA Center controller reported an unsafe situation due to lack of coordination from the Front Line Manager and the Traffic Management Unit. Controller also made reference to the added sector complexity due the metroplex project changes.
