Back To The Future, Part II (1989)

Doc Brown's time machine works its magic once more in this merry sequel to Back To The Future. 

Michael J. Fox is on board again, along with Christopher Lloyd as the eccentric scientist. They time travel to the years 2015 and 1955 in attempts to ward off various dark destinies.

Cast and special effects are good, but the complex script could use a lighter touch. It certainly helps to have seen the original. A third and final Back To The Future sequel followed in 1990.
