So you have all seen the commercials for this by now. Looks like it might be funny right? Or at least some combination of stupid/funny to at least be enjoyable. Sometimes a movie just comes right out and nails it's mission in life with the title. There's no guessing what you're gonna get when you go see the movie, and the movie doesn't have to pretend to be something it's not.
Take for example "Dude, Where's My Car" or an even better example "Snakes On A Plane". That movie was about one thing, and one thing only: Mother Fracking Snakes on a Mother Fracking Plane.
So anyway, Hot Tub Time Machine, who's in??
