I'm not friends with the person who swore this was funny.
It's amazing how low this series has gotten. The first was silly and dumb but still managed to be funny and actually clever in its spoofing. The second one poured on the stupid and the soots were less inventive. The third tries way too hard to be stupid and unoriginal in anything it attempts.
Some of the cameos are what makes this a 3/10 and I may have smiled at a gag once or twice.
