Airspace Structure; Procedure
On arrival into ZDV airspace; HALEN intersection; we received five Different STARS from the FAA Traffic Management Unit (TMU). First the BOSSS; then the ZEPYN; then the PEEKS; then the JAGGR; and finally back to the ZEPYN arrivals. Just wanted concerned parties to be aware of the high workload this NEXT GEN ATC system is creating. We also went from being 25 minutes early to 7 minutes late.
B737 Captain reported four STAR changes by ATC arriving DEN before being reassigned a previous arrival; costing 32 minutes.
