Hot Tub Time Machine DVD- Good quality entertainment. A schoolboy humor comedy to see with friends. Some valves are funny, often scatos (based on vomit and poo, obviously), and the initial idea (4 mates are teleported unwillingly into the 80s) rather enticing. However, it is a little on our end. We would have liked more about madness and a better exploited by the writers. References to the 80s are too few when there were material to go further. Much of the film takes place in a ski resort limiting action.
