Hot Tub Time Machine Is Not "All Wet"

It's been out for 5 weeks, but I finally saw Hot Tub Time Machine last night.  What a fun movie (if you don't mind the constant barrage of F bombs).  The title pretty much sums it up.  Four guys travel back to 1986 by way of an energy drink supercharged hot tub (yes, you read that right).  John Cusack is the 'star' but the real lead role goes to Rob Corddry (Old School, Semi-Pro) as Lou.
Lou is a Lou-ser (get it?) and after what appears to be a suicide attempt his buddies whisk him off to a dilapidated ski resort for a weekend getaway where they proceed to do the said time traveling.  Queue the 80's music and movie spoofs!  There are some neat cameos by Chevy Chase, Crispin Glover (Back to the Future) and William Zabka (The Karate Kid).  There's even a performance by Poison (not really, it's a bunch of look-alikes up on stage lip-syncing).
All-in-all it was a good way to spend 90 minutes.  It's not blockbuster material but I'd recommend it for a matinee or video rental.  Rated R for language, drugs, nudity and 80's fashions ;-).  Check it out....
