The psychology behind a sequel is simple: more of the same, and usually bigger. After all, since the first film was a great success, why change a winning formula? While it's generally accepted that a follow up won't match the original, producers can always rely on dollar signs as a motivating force.

However every so often that rule is broken, and a director will try something different with a new instalment. From a shift in tone to a complete change in storyline, there are sequels out there that mean more than an increase in budget and a digit jammed onto the end of the title. Here we take a look at ten of the best/worst examples.
