2020 5.29. Going back from season 6 , I have to appreciate the great acting skills of doc.wells and the vitalty of team Flash in this episode. But it makes me wonder why are those good things kind of missing in the following seasons:especially in season 6 ,Barry is depressed and Iris is trapped ,team Flash is low spirited ,Nash Wells loses his cleverness and mysterious charm.and the talk is not convincing enough. We need the vitality of Flash again,it needs to be more inspiring again!By the way why the special effects declines when techonology develops.
