What I liked: Craig continuously showing his disdain of being on this adventure with Stan, Kyle, Kenny and Cartman, Stan saying Craig is being a dick, and then Craig recounts all the stuff that has been going on, South Park being attacked by guinea pigs, including guinea rabbits, guinea bees, amongst other things.
Good episode. I don't hate it as much as most people do, but it's still far from a great episode. It has some good laughs and an OK plot, but the execution is mostly crap. So my final grade is going to be in the "C" range, I think is fair
