Oh I liked the Hangover, although the humor in the Hangover was
   over the top in quite a few places. Hot Tub Time Machine, the
   part I saw, was like a great goofy throwback to 80's movies with
   a 'now' twist. The thing I get a kick out of is when they have
   young actors who didn't live through that era having to
   effectively play the part of 80's characters. Some of them get
   it "dead on" and others you can tell are just playing the
   stereotypes of the era. "
