Up the Creek Reviews
The premise is absurd from the outset, but serves as a springboard for the rest of the movie. It focuses on four lay about collegians who, according to the dean "Have the distinct honor of being the four worst students in the entire country. You're not at the bottom of the list, you are the bottom of the list!" - Dean Burch. This distinction is only further ingrained by the fact that they achieved this dishonor at the nation's worst institution of higher learning.
In an effort to finally rid the school of these academic hangers-on, including Matheson's character, Bob McGraw, now in his 12th year of matriculation, Dean Burch bribes them with degrees of their choice in exchange for competing in and winning an inter-collegiate river rafting race.
From there, it is part road trip - getting to the competition - and part river rafting adventure where they must overcome the not only the rapids, but the sabotage efforts of other teams, including a military academy squad headed helmed by an overly gung-ho captain, as well as a team of Ivy League pretty boys, determined to win the race at any cost.
The cast is rounded out by a plethora of 80s era one-note actor and also-rans, including Dan Monahan - "Pee Wee" of Porky's fame. But it also features James B. Sikking (Doogie Howser's dad) in the uppity-rich-ivy league-alum role, Tozer, so, bonus for that.
All in all, a very serviceable 80s college hi-jinks/sex romp flick.
