I thought it was an average, almost meh episode. Them being Canadian was a funny touch, and the dead Queen was a laugh. The rest of it - except for Butters and the girl (I won’t spoil it...you have to see it) - felt like they mailed it in.
I haven’t watched it in years, but am generally a fan of Matt and Trey’s work. They nailed it on transgenderism more than a decade ago (15 years?) with Mrs. Garrison the “lesbian,” which is pretty amazing.
Traveling today, will try to watch tonight when I get home.
