Episode 5 justifies the whole thing!
Just amazing stuff they threw at us. It very well may be said it’s a bit retcon-y, but IMO, I feel it all fits very organically with the events of the first movie.
I DO think it would have been possible to have done this idea in a single movie rather than a series, but at the very least they limited themselves to 6 episodes and not longer. Can’t wait to see the finale.
