YES. That was a good send-up of how stupid those “first person” movies are and what an idiot Randy is. Randy has really become a top-notch character in the last few seasons starting with, IIRC, the Batdad episode.
Nah, it just seemed like a predictable dénouement—was hoping for something unexpected. And they already did the “Cartman fights the midget” thing.
Not sure how you can say Cartman v Wendy was predictable and then compare it to the fight against the midget, seeing as how Cartman beat the midget but lost to Wendy.
You’re correct, I’m afraid. I have neither the sensitivity to nuance, nor the dexterity of expression necessary to transact a proper analysis of the many discrete imbroglios of Eric Cartman.
I just wanted you guys to think I was cool.
It’s ok man. You don’t have to lie to kick it.
It’s okay.
We never thought you were cool. 
Referencing There Will Be Blood was unexpected.
Otherwise I’m in full agreement with the meh consensus here.
Wait, they refed There Will Be Blood? I saw that movie! And I still didn’t see it…when?
After Wendy kicks Cartman’s ass, she sits with her back to the camera, Cartman’s bleeding body next to her, turns her head, and says over her shoulder, “I’m FINISHED!”
