It is absolutely worth seeing, I agree, though I don't consider it absolutely top-tier Spielberg (that hallowed realm belongs to Jaws, Close Encounters of the Third Kind, Raiders of the Lost Ark, E.T. The Extra-Terrestrial, Jurassic Park, Schindler's List, and Saving Private Ryan). I think Tar, The Banshees of Inisherin, or Aftersun (shamefully not nominated for Best Picture/Director) deserve the top prizes more.
My thoughts in full here, if you're interested. :)
