It's a real pleasure to be able to own the BTTF trilogy on DVD, not just because the films are so good, but also because the extras are tremendous.
By now, no one needs to be told the plot, but Zemeckis tells a brilliant tale throughout as our hero Marty zips forward and back in time righting wrongs and making sure all goes smoothly for his parents and his children whilst trying to avoid destroying the Universe by creating a time and space paradox.
It sounds confusing, but Zemeckis makes time travel fun and it's not worth trying to think too much about it and spoil the enjoyment.
The acting is tremendous throughout, with Christopher Lloyd the real star as the crazed Emmett Brown but there's not a dodgy performance to be found. My personal fave is BTTFII, where Marty has to retread his own steps in 1955, visiting the same locations where he is already in place and trying to avoid running into himself - terrific stuff.
The brilliant extras (over five hours worth) consist of cut scenes and wonderful making of documentaries from the time the film was made and also more recently filmed look-backs from the cast and crew. These are worth investing in the package for alone and the extras put shame on other releases that really don't go anywhere near enough to town on them.
These films are what movie-making should be all about; a great tale, excellently played out with top performers and a whole load of fun to boot.
