The film draws effectively on the power of two seductive performances--those of Nico Evers-Swindell as William and of Camilla Luddington as Kate Middleton....It's a familiar story and an entertaining one.
If the movie had gone all-out camp, it could have been a classic. If it had gone all-out cheesy, we could mock it more mercilessly. As is, William & Kate is as benign as the actual couple.
William & Kate is designed almost entirely as an opening act to the real wedding, a short guide to the players. It succeeds simply by not giving anyone a single reason to believe W&K won't live happily ever after.
If the makers of William & Kate had loaded up their movie with higher-octane performances, and if they'd aimed for more humor, flash, and cynicism, they might have come up with a more engaging piece of camp. Instead, they deliver a royally forgettable bit of banality.
