Trying to recapture your youth.
If you have seen other movies from Wright, Pegg and Frost then you know what to expect. If you haven't seen anything from these guys then get ready for a film with good visuals, comic gags, and a splashing of action. Nothing is taken too seriously and it seems that they had a blast making it. This is very much a film worth seeing for the enjoyable ride.
By the end of the movie they are focused on more than just reaching the last pub. They have managed to stumble into a battle for mankind's future with there actions being pivotal to the outcome. Will they come through and save the human race?
