Rather than regurgitate the Empire in the sequel trilogy and The Mandalorian, they should have invented a brand-new enemy.
Additionally, I wish Stormtroopers would actually pose a threat rather than be disposable fodder ala the putty patrol in Power Rangers. It’s a wonder they’ve conquered anything at all.
For the sequel trilogy, I agree. For The Mandalorian, not so much. It makes perfect sense given the time period of the series.
