I personally loved it, will be watching it again when it premieres on UK tv this Friday. Cartman throwing a fit at the beginning when Stan, Kyle and co stormed his makeshift border fence was funny, along with Butters getting a leaf blower as a present.
Best part? Randy walking outside to find his driveway covered in leaves while screaming "NOOOOOOOO!"
