A wonderful final crossover between the arrowverse characters which makes up for the lackluster episodes that came before it. Seeing Oliver Queen/Green Arrow/Spectre was an amazing sight to see along with diggle, Singh and Wally. Also seeing Barry and Oliver's dynamic once again is amazing and you realize that this is the last time these characters interact and it's really the end for the arrowverse. Wally got some redemption by having barry apologizing to wally which is basically the writers apologizing to Keynone Lonsdale for underutilizing him. My only negative is khione. It's literally frost again.
